See all stuff on the "Verizon" section of the app drawer (which by the way, you can delete the tab), start there. Anything else you don't use or don't care for, freeze it. If you need it again, or the phone is acting weird, defrost the frozen app.
Now if you're deleting, like I did, you'll want to pull the list off of CleanTool and opening the process in Notepad. Scott pretty much narrowed down for us. MrSmith also has a list of his own floating around on XDA, also on the CleanTool thread I believe.
