I believe that the following bibliography for the study of Christology was compiled a few years ago by some of the faculty at Southwestern Baptist Theological Seminary.
Strongly Recommended Texts:
Denney, J. The Death of Christ. Tyndale,1951; Paternoster, 1997.
Green, J. B., and M. D. Baker. Recovering the Scandal of the Cross. Paternoster, 2000.
Hawthorne, Gerald F., and Ralph P. Martin, eds. Dictionary of Paul and His Letters. Downers Grove: InterVarsity Press, 1993
I. H. Marshall, The Origins of New Testament Christology (IVP, 19902)
There are important articles on most of the key terms in the four IVP reference volumes: the required Dictionary of Paul and his Letters (DPL), as well as Dictionary of Jesus and the Gospels (DJG), Dictionary of the Later New Testament and its Developments (DLNTD), and Dictionary of New Testament Background (Consult all 4 volumes, since sometimes a topic is covered in more than one volume). See also the articles in NIDNTT (not quite so up-to-date and patchy) and the more technical articles in TDNT.
Relevant articles in the four IVP Dictionaries of the New Testament.
