People typically have a one-piece driveshaft made to eliminate the carrier bearings; as that is what tends to go out first. There are also degree shims that can be added to correct pinion angle after lift. The torsion bar cranking 'tool' is a 27mm socket and a breaker bar or impact wrench... and can be found anywhere that carries larger individual sockets. I got mine at the local NAPA; Sears carries them as well. Some people have used a 1 1/16" socket since its close in size and they already had one. The degree shims should be available through any 4x4 shop/wholesaler. www.independent4x.com has them.
