Wish I could help more, sounds like a good plan!
Planning on using an early model np231, or a 207? Some things to consider: spline count, year, and cable speedo adapter.
86 will more than likely need a 207 for a direct, easy swap. 231 you'll need from 87 to 90, behind anything but the ax-15, but with it you'll need the correct speedo cable and possibly a new gauge cluster.
This is, of course, neglecting full-time cases, but I can't really help you there.
Just about your only choice on front axle is a dana 30, unless you want to find a rubicon LP44, which is only marginally stronger. Avoid the disco dana 30, or anything from a TJ and you'll be fine.
Oh, and if you're gonna turbo it anyways, you should consider an ax-15 or nv3550/np231 swap. Search on those, I don't have all the necessary information. I do know you'll need an 87-90 cable adapter, cable, and cluster (again).
someone chime in if I'm spewing crap... I'm just trying to lend any information I can!
