I caution you to avoid "theological politics" as that would be dishonest and not befitting a Christian.
The "New Perspective" is, of course, not new. It is just not the view of the Reformers. It is still the view Judaism holds (although they do not apply it to Paul).
Important NPP scholars include Sanders, Stendahl, Dunn, Gathercole, and Wright....BUT you need to add tgat all of these men hold different conclusions. The NPP was an appeal to look at the doctrine of justification as it relates to first century Judaism apart from 16th century issues.
