Since 1 Peter is the focus of my study, I'd like to share some of my thoughts on the most helpful resources for teaching and preaching 1 Peter. A bibliography has been supplied at the end, so key works will be referred to in an abbreviated manner.
1. For Preaching (focusing mostly on modern evangelical scholars)
Let's start simple. The bottom line is, if I'm preaching through 1 Peter (as I've had the privilege of doing at my local church at different points in the past year), I head to Jobes (2005), Grudem (2009), and Witherington (2006), more-or less in that order. My reasons are as follows: Dr. Karen Jobes has written what is frequently regarded as the top evangelical graduate-level commentary. Indeed, I would consider her possibly the top scholar on 1 Peter currently in evangelical scholarship. Her Baker Exegetical commentary is definitely a solid exegetical work but is also surprisingly accessible (i.e. it's not overly-technical). Her biggest contributions, perhaps, consist of her knowledge of the Septuagint (and its use in 1 Peter) and her alternate proposal regarding the social context of 1 Peter (i.e. her "Roman colonization" theory for the background of the recipients)
Wayne Grudem comes next because out of all the scholarly commentaries, his is possibly the most accessible. Grudem is enjoyable to read and challenges the consensus in a couple places. I often disagree with Grudem, but he provides a solid yet simple commentary.
Ben Witherington's social-rhetorical commentary is next, mostly because he excels at the social-rhetorical aspect, providing some material that others do not. Also, I find myself in agreement more with Witherington on the issue of foreknowledge in 1 Peter than with any other scholar (quite possibly Witherington will prove to be one of my favorite sources for my dissertation). True story: Witherington's material on the background and social-rhetorical material in the New Testament is regarded so highly in some circles that the seminary I got my M.Div. at, a very strong dispensational seminary, ironically required us to read Witherington's commentary on Revelation in its entirety for that class. For a dispensationalist seminary to require Witherington's Revelation commentary as a textbook is comparable to the Boston Red Sox hiring Derek Jeter as a hitting coach!
A fourth source that is invaluable for preaching 1 Peter, depending on the passage, is D. A. Carson's extremely thorough discussion on the use of the OT in 1 Peter in Baker's Commentary on the New Testament Use of the Old Testament.
If forced to pick another more-or-less accessible evangelical commentary, I would probably go with Peter H. Davids' NICNT commentary (1990). I am extremely partial to Douglas Harink's thought-provoking theological commentary (2009), but this is less helpful for preaching and more helpful for group-discussions or Bible study (though I realize some would question whether there should be that strong a distinction between the two). Honorable mention also goes to Thomas Schreiner's NAC commentary. The NAC series is generally very accessible to those without an extensive theological education.
At the more theological level, I have found only two accessible works that I really like so far: Andrew Chester and Ralph Martin's The Theology of the Letter of James, Peter, and Jude (1994) and Gene L. Green's brief article on 1 Peter in the New Dictionary of Biblical Theology.
In addition, those preaching through 1 Peter should naturally make use of more general background and introductory works. I am especially partial to The New Testament in Antiquity by Gary Burge, Lynn Cohick, and Gene Green (2009).
As far as classroom work, if I ever get to teach 1 Peter, at this point I'm leaning towards Jobes for grad-level and Grudem for the under-grad level, for the reasons listed above. I believe both Grudem and Schreiner would be especially accessible to the layperson in the church or the college student simply taking 1 Peter as an elective.
2. For in-depth study
This section is for the student/pastor/etc. who wishes for in-depth, grad-level study of 1 Peter
To start out simple, I would recommend Elliott, Jobes, Goppelt, Selwyn, and Witherington, in that order, with the somewhat-less-accessible WBC commentary by J. Ramsey Michaels coming in after that (not Ramsey's fault! The entire WBC series is, in my opinion, difficult to use! Despite this I have to acknowledge their scholarly excellence).
To a certain extent, John Elliott's Anchor Bible Commentary (2001) remains the standard for scholarship. I've read through the entire thing (almost 1000 pages!!) and can attest that even if you disagree with his views on the social setting of 1 Peter, the letter's authorship, etc., this book is well-worth its weight in gold. The bibliography alone is staggering in the wealth of information it provides.
The WBC series, of course, is highly valued for its exegetical discussion, and Ramsey's work (1988) is no exception. It is, however, a slightly more difficult commentary to use than some of the others, due (in my opinion) to the layout of the commentary.
Leonhard Goppel's commentary remains the standard for many, and I have benefited greatly from it. I believe it is currently in its 8th German edition (1978). Goppel's work also remains what is probably the premiere foreign-language commentary on 1 Peter.
Speaking of foreign-language commentaries, Ceslas Spicq's commentary on 1 Peter, while not as well-known as his work on Hebrews, is worth looking at. It's extremely difficult to find, however; to my knowledge only one library in the US has it, and they are not eager to lend it out (not that I'm bitter or anything :). Fortunately I found my own copy via ABE Books at a reasaonable price.
Among the classics, the reader should consider F. J. A. Hort (1898), E. G. Selwyn (1949), Bo Reicke (1964; the original Anchor Bible commentary), and F. W. Beare (1947). Selwyn is still considered by many to be the standard for Petrine commentaries.
The commentaries by Jobes, Witherington, and Davids have already been noted in the previous section, and their value should be emphasized for in-depth study as well. Surprisingly, I would still consider Grudem as one of my top commentaries for serious study, mostly because he has some perspectives that "go against the grain," so to speak (e.g. his view on what the prepositions in 1:2 modify).
J. N. D. Kelly (1969) and Paul Achtemeier (1996) also provide two of the top academic commentaries on 1 Peter and should be consulted.
For German sources, I can also recommend Norbert Brox (1979) and Reinhard Feldmeir (2005). I believe Feldmeier's commentary has been translated into English by none other than Peter H. Davids, who has his own commentary, mentioned above (I haven't seen the English translation, though; I've only worked with German, not because I'm good at German but because my adviser pushes his students to work with the originals). In addition, Karl Hermann Schelkle's work (1970) has some useful material and is probably my fifth choice for foreign language commentaries (after Goppelt, Spicq, Feldmier, and Brox, in that order).
At the theological level, Harink, Chester/Martin, and Joel Green (2007) all provide some valuable material.
The importance of Carson's work on the NT use of the OT in 1 Peter has already been noted, and should probably be the first stop for any study on that topic.
2. Articles, essays, and monographs
It's a bit more difficult to recommend anything in this category, due to its specialized nature, but I would like to bring the following to the reader's attention:
John Elliott's A Home for the Homeless (latest edition is 2005) is a classic, though very few scholars agree with him completely. Elliott is pretty much "the man" when it comes to a social-scientific perspective on 1 Peter (see also his What is Social-Scientific Criticism [1993)]. However, for a very different approach, the reader should note Feldmeier's Die Christen als Fremde (1992), a broader work that nevertheless interacts with 1 Peter and Elliott's views. Perhaps the best critique of Elliott comes from Moses Chin's Tyndale article "A Heavenly Home for the Homeless."
For other monographs, J. Dryden's Theology and Ethics in 1 Peter (2006) and Troy Martin's Metaphor and Composition in 1 Peter (1992) are two of the most interesting. For dissertations, Edward Glenny's "The Hermeneutics of the Use of the Old Testament in 1 Peter" (Dallas Theological, 1987) and Ervin Starwalt's "A Discourse Analysis of 1 Peter" (U. of Texas at Arlington) are both good discussions of their respective topics.
For articles and essays, I highly recommend Jobes' BBR article "The Syntax of 1 Peter. Just how good is the Greek?" on Petrine authorship (warning: somewhat technical!), as well as her essay "The Septuagint Textual Tradition in 1 Peter." The latter should be read alongside Carson's work when researching this topic. For NT use of the OT, I also enjoyed Jocelyn Williams' article in RTR entitled
"A Case Study in Intertextuality: The Place of Isaiah in the 'Stone' Sayings of 1 Peter 2" as well as Gene Green's very-accessible Tyndale article on "The Use of the Old Testament for Christian Ethics in 1 Peter." On a different topic, I also was challenged by Joel Green's "Narrating the Gospel in 1 and 2 Peter" in Interpretation (2006).
There is, in my opinion, a relative lack of material on Petrine theology (though Green's well-written "Narrating the Gospel" does fit into the theological category). For the interested reader, however, there is a certain article on a Petrine theology of prophecy coming out in a future BBR.
Finally, let me also point out Colin Hemer's classic article in Expository Times on "The Address of 1 Peter" (Hemer, of course, is to NT backgrounds what Hank Aaron was to homeruns!)
There's a ton of other worthwhile monographs, articles, essays, commentaries, etc., but hopefully this will be enough to get started. If you disagree or feel that I've omitted an absolutely key source, feel free to let me know (or post it in the comments section).
One more thing. If this essay isn't in-depth enough, then consider the following three surveys of scholarship: Eugene Boring in the journal Word and World (2004), Mark Dubis in the journal Currents in Biblical Research (2006), and Robert Webb in the book The Face of New Testament Studies (2004).
(with special thanks to Dr. Gene L. Green of Wheaton College for his directed study with me on 1 Peter. His work with me was essential for my own studies on 1 Peter, especially in understanding what the key sources on 1 Peter are. It was Dr. Green who first introduced me to the work of John Elliott, which will probably play a major part in my dissertation. This essay reflects my own opinions and not necessarily those of Dr. Green, whose views would naturally be much more informed and interesting than mine)
