i'd suggest the terra grapplers, i just put a set on my truck and love them, they're great on road, hardly any road noise, and so far they've easily handled everything i've thrown at them offroad (some hard packed dirt roads, mud, and pretty sandy soft stuff)....
i was in your shoes not too long ago looking for new tires and did alot of reading on the forums here, finally helped me decide on the nittos....norcal kinda helped push me in that direction (thanks buddy
)...
also, like norcal said, if you're looking for a leveling kit, check out prgproducts.com they have great stuff, i just had some new shocks and coilovers installed by them, and i love them....
welcome to the forums man, any other questions, we'll be happy to help you out....
