The work left to do is pretty straight forward. The axle can be had for $100 plus a few more hours work and you'll have it licked. I think I would finish it up, make sure it's a clean swap and put it up for sale. And if you decide you don't have to sell, all you hard work to date will be even more worth while.
If you do decide to sale, check out http://www.nc4x4.com/forums/. Another great forum that's local to you. I'm sure you'll have plenty of interest in a decent MJ 4x4.
Good luck and hope you don't have to sell.
