I rooted my Bionic using the one click Droid 3 method, worked like a charm!
Installed Titanium Backup. Since I have purchased the pro version I went through freezing stuff - if I froze an app and the phone went wonky I unfroze and left it...
Using that method, here are the apps I've frozen with no issues:
