I ordered the Pro Comp 2.5" level and it works perfectly fine for me. As far as brand goes, Im not sure it really matters. I can't think of any "bad quality" leveling kits out there.
As far as wheels go, offset is all about how much of an aggressive look you want. I can't imagine any benefits or drawbacks of having the tires stick out past the fender. All about how you want the truck to look. I have 20x9 XD795 with 18 offset and they stick out of the fenders about 1.5". Perfect for my taste.
And as far as tires go. Nitto is a good quality brand, especially for the prices they offer. You can't really go wrong with anything that has Nitto stamped on it. They have the all terrain tire (Terra Grappler) that Ive had before and performed great for what I ised it for. They have the mud terrain tires (Trail Grappler and Mud Grappler) and both are fairly good tires I hear, never had them. But depending on what size wheels you want, a 33x12.50x18 or a 33x12.50x20 would be good routes to take. A 305 55 R20 tire comes out to be about 33.2" in diameter. So that would be the way I would go if I were wanting a 33" tire. Hope this helps!
