I'm not gonna be doing this anytime soon.  I still have to get my lift, locker and diff gears first, but I thought someone might be interested.  So does anyone use lower Tcase gears in their GV/Tracker?  I know people rave about them in Sidekicks and Sami's.  Also are they very usefull if you don't do much rockcrawling?  I'm mostly on dirt trails, washes and sand only the occasional rockcrawling in tough spots.

Oh yeah, in case you are interested look at

For your purposes I'd say the money would be better spent on suspension, tires, and the rest of your plans.  High range has no reduction in Kicks and GV's so lower gear sets won't help you going down the road and your wheeling doesn't sound like it needs uber low gearing.

If you can find some lower axle gears to match the tires but aside from that, spend the money elsewhere.
