Dude, that totally sucks.

Knowing how busy you are I think you are in trouble. You'll have to take YJ in to a shop and see what they tell you. If you had more time (even this weekend) I'd say lets pull the tranny and clutch out and inspect. We can't mess with the tranny (atleast I wouldn't), but the clutch we could fix, also we could check the rear end.
Call me later and if you need help let me know.
