Starting with the class list is a good idea. Yes, most of them are functional, but some are still missing (and some are only there if you have a patch, or require a patch for certain parts to work properly).
In the spirit of just getting a thing done, here's a GoogleDocs sheet with the state of classes, as I observe them in my version:

(I'm not familiar with individual quirks/bugs in a lot of these classes, especially the hybrids. If you know something, please add!)
Feel free to add, comment and contribute (or steal wholesale and put somewhere more useful, if needs be). Add new sheets if you want to put in things other than classes. Basically, if it can be useful, go for it!
It should be open for anybody to edit - I don't think we're gonna have anybopdy mess with it, but if somebody wants to ruin the party we can deal with that when we get to it.
