I also suggest the Play-by-Post part of the forum. While the games don't last forever, there are plenty of possible characters there. Many of those have been playtested and repaired as well, so you know they are pretty solid.
Oh, and my suggestion for your pre-made characters is simple: Have a good spread of these.
High Level Spellcaster (sorcerer, wizard, etc.)
True Believer
Were-form
Pure Mortal (make him a real badass, otherwise people tend to avoid using them)
Changeling
The other character concepts are more limited, and might not be best for new players. I mean, Feeding Dependency and Involuntary Human form can be a real pain, and when you just start out on a game, you might not want to face something like that.
