That's a pretty simple swap.
Since you're not removing the pinion gear, you don't have to worry about pinion depth.
I would say that all you need to do is: determine the backlash as it sits, and install the new carrier with whichever shims it takes to give the same backlash, and the proper bearing preload for the new carrier bearings.

Many transmission shops or supply houses will stock the special replacement shim kit for these rear ends. It consists of two large shims that allow the fine adjustment shims to be installed into them. This package is then installed on each side of the carrier.
