Good writeup simple.

Setting pinion depth is important, as you want as much of the pinion contactying with the ring gear as possible. Some diff setups are easier to see inside when partially assembled than others. I usually try to shim the pinion till it almost touches the diff cup, so I know the max amoiunt of the inion teeth are contacting with the ring. Then shim the ring gear as described above.

New gears will be notchy, but will wear in. You might have them smooth through most of the rotation, then they get notchy in a few teeth, that is fine, as they will wear in.
