to change the flywheel you can slide the trans back but it's a pain to do that way. Stock gears should be fine, the rearend I would wait until you get some performance stuff done, and get an idea how you want ot use the car, that will dictate what gears you want to run (I would advise getting rid of the factory rear and going aftermarket when you decide to upgrade, the factory one is junk)

If it is a flywheel it should not be hard at all to slide the trans back I took a manual trans out of a camaro from the junkyard in like 20 mins. auto is another story cause the bolts on the bellhousing are harder to get to because you cant move the trans first.
