8.25 8 1/4 Rebuild and modification

I want to change the ring and pinion on my axle, install a rebuild kit, rebuild the sure grip unit in it, and add disk brakes from a Jeep Cherokee. Can I do this on my own? What tools/calibration equipment do I need? If not, what is a fair price for the axle rebuild? Thank you for your time and input!

I bought a 3.21 ring and pinion and a master rebuild kit.
