Will a 2" AS level kit and **** Cepek DC-1 Black 17X9, 6 on 135, 4.5" backspacing, 12mm offset, with a 33X12.50 Mickey Thompson work well for offroading?

Here's the photoshop on my truck:

 

honestly, if you're going to offroad frequently, ditch the spacer, and go up to 35's and a suspension lift. that leveling kit puts your cv's and ball joints at less than an ideal angle, and coupled with hard offroading, don't be surprised if you find torn cv boots and accelerated wear on ball joints.
