Here are a few options from Solo Motorsports.
One being the 14" LT kit (cost less than TC)
The 18" LT kit (still works with 4x4 with modified axles, but is twice the cost of TC)
They also have mid travel upgrades.

Personally, I've had a great mid travel set up (extended travel ICON 2.5 coilovers, Light Racing UCAs). I had a ton of travel, but wish I could have more. I'll be aiming towards the TC 13" LT kit or the SMS 14" LT kit. I haven't decided yet.
As for the rear, it depends on how crazy you want to get. The way I see it, there are three options.
1: 4link the rear, build custom coilover shock tower in the rear cab, cover it up some how to keep cab enclosed, but have the covers be removeable for maintenance. Run bypasses as well. Modify fenders and wheel wells.
2: Leaf spring swap with chevy 63" leafs (modified packs of course) and bypasses, still cutting into the cab, modifying the fenders and wheel wells.
3: Keep it mid travel with a good resi shock. (won't gain travel, and will likely bounce around trying to keep up with the front. I had this issue with a built mid travel front, so I can only imagine it'd be worse with a LT front.)
Of course, there are many many options you can do, and the possibilities are endless if you or some buddies have any sort of fab skills.
Just my $.02
