The International Greek New Testament Project has a bibliography page with names (leads) to follow through on. (see "igntp.org")
I don't know where you are in the spectrum, but the preview portions of Peter Kyle McCarter's Textual Criticism: Recovering the Text of the Hebrew Bible may be worth a look on Google books (id=Dg86WeszmtAC). If you already read Hebrew, then Emanual Tov's Textual Criticism of the Hebrew Bible is a meatier work (id=U1UfMyO-RiEC).
While this might look a little out of the ballpark, this broader study (solidly college level, but you don't need biblical language skills to read it) will teach you some enormously important things that either apply to biblical study or to understand what others are saying about textual criticism and more. Also available to glimpse on Google books, Jerome J. McGann's A Critique of Modern Textual Criticism (id=_EKipG36yiAC). (Not permitted to post the full url just yet, sorry)
