Replacing main tranny bearing on door side and quad seal

A few months ago I replaced the the rear tire on my 05 bulldog and when I did I tightened the drive belt tighter than it was before cause I noticed when my bike was pulling hard in 1st and 2nd I could feel it jump a tooth. I probably put 600 miles on it since then but on Sunday I was out on a nice 250 mile trip and I looked down and half my belt was missing (threaded/melted) everywhere and it was tracking away from the tranny on the pulley. i pulled the outer cover off and noticed a little (very little ) play in the tranny pulley. I also noticed tranny lube leaking from between the two output shafts so I think that the quad seal could be leaking, the main larger seal looks to be fine.

Question I have is, am i going down the right path
replaceing:
main bearing
quad seal
door gasket
belt

or is it something else wrong?

Also what am I getting into by opening up the door and pressing the main bearing out of the door? is there a bunch of stuff going to get out of place when i take the door off? What should I or shouldn't I do?
