I'm going to end up getting a t-loc and 3.73s and the only 7.5" I can find for 4.10s, 3.90s, and 3.73s are Motive brand? Does the OP and myself have to get anything else for the install? I've been looking around and I've heard bearings mentioned? Also, is the OP and myself going to need to drop some coin on some new gear oil, or should the shop have that and add that into labor costs? I'm pretty naive in the drivetrain area if you can't already tell.

Bummer. I guess I can try to talk the the mechanic just to see on any guarantees and what not. Can the mechanics usually rewrite the tune, does it need to be dyno tunes, or can someone like Mike at tuningsuperstore rewrite it?
