Alpha and Omega Ministries, The Christian Apologetics Ministry of James R. White
The Roman Catholic apologetics section will probably be a great help. He has dealt with the popular Roman Catholic apologists since around the time they started comming out of the wood-work, and primarily with those Roman converts who used to be "Protestant" (read:non-Roman Catholic). His debates are shining examples of the failure of Rome at every turn to be able to defend herself consistently under criticism.
From what I understand, and I don't run into this a lot because Romanism is very, very weak in my area (there are plenty of Papists, but they don't try to convert anyone, my main battlefield is pluralists/atheists), many of the new apologetics tactics of Rome are emotionally based, something they probably did learn from post-evangelicalism. They appeal to peoples emotions; what people like, how people "wish" it was. In reality, they are pandering to the sinner's idols, and raising them up to be the actual authority embodied in mater ecclesia. It's such a sham.
Other tactics include faulty logic in attempting to destroy the authority of Scripture (this is a BIG ONE), mis-quoting church fathers (I don't want to say lying because often the guy on the street didn't go look up the church father, but they read it in one of the above mentioned author's books and THAT author is the one that is lying about them), and even mis-quoting Martin Luther (the blog of James Swan,
Beggars All: Reformation And Apologetics can help with this. Mr. Swan is a Luther scholar extraordianaire).
I'll try to think of some other resources, but I know that both Dr. White and Mr. Swan are excellent in these two respects, and everything is available online for free.
Please accept my apology, sister Meg. Junior Alzheimers is setting in too quickly.
