Go for it! The Revtek lift is a great product and easy to install. Your ride will firm up a bit and give you better handling with less body roll in the turns. The Runners should come this way from the factory. As for tires, go with 265/70-17 or 265/75-16. Revos are ok, but you may want to look at BFG AT KO or TerraGraplers. they are a little more aggressive offroad and perform well on the road in all conditions.
