Need Help w/8.75 Gear Swap

First time attempt to swap ring/pinion and rebuild an 8.75 (489 Case) and need some help and insight. Specifically, with setting pinion depth and installing large and small end bearings. Let me explain my situation and list out questions:

Situation:
Ring and pinion are 4:10 Richmond and have a limited number of specialty tools in my garage. Starting point is the bare case, but both large and small pinion bearing races have been replaced.

According to what I've read, if I don't have a pinion depth checking tool, I can use the trial and error method of assembling the unit and checking pinion depth via the gear/teeth pattern method. So, I should start with about .035" shim(s) on the large pinion end, install (Press on) the large pinion bearing, install pinion in case, insert small end pinion bearing, and press on small end bearing via torqueing yoke to spec. Check pinion depth. If incorrect, uninstall add/delete shims, re-install, and recheck. if correct, uninstall, add crush sleeve, re-install, and re-torque to spec.. (Much abbreviated instructions)...

Questions:
1. Does the large end bearing need to be "Pressed on?" If so, can I use a large 3-jaw puller or do I need to take to a machine shop.
2. If I have it pressed on and the pinion depth needs to be changed via adding/taking away shims, will I be able to get the large bearing off and reuse? Bearing to pinion tolerances seem tight...
3. Do I understand it correctly that the small end bearing is pressed on via tightening the yoke nut? Also, same question as large end is pinion depth needs to be changed.

Thanks for anyone's help and sorry for the long winded post!
