Doug, regarding the assumption that Mark and Matthew are less "Pauline" than Luke and John, and therefore, keep a more "authentic" record of the early Christian tradition, you really should read Eisenman's "James, The Brother of Jesus", because it utterly debunks that notion. Eisenman makes too much of certain "themes" and "reversions" [such as the 'cast out', 'whiteness', 'eat', etc] found in the synoptics and John, but he's absolutely thorough in demonstrating the anti-Jesus famiily [anti-Qumran] agenda that pervades Mark and Matthew. I was blown away. It's not an easy read, especially for me, a non-english native speaker, but it's based on fresh research, published very recently - and Eisenman is one of the scholars involved in the publishing of the Dead Sea Scrolls texts.
