sorry to not really answer earlier, was in a rush and just wanted to point you in the right direction.

(1)dunno what you would use for a 2" lift, like the sticky says a 3" is just as easy and looks better and is more functional. there is also a body lift kit here http://4crawler.com/4x4/ForSale/KiaSportageBodyLift.shtml what exactly are you lifting for?

(2)cant find any fender flares for my ride yet, working on fabbing some up. its a ways down the list though.

(3)http://www2.partstrain.com/store/?N=10924+1646+4294967269+9357 this is a universal grille guard, i think it looks pretty good. i know there is a bull bar out there as well.

(4) i got some 15x8 rims with 4 inch rear spacing, and i havent had a problem at all. no rubbing at all. i think anything aftermarket with a 5x5 1/2 lug spacing should work fine.
