If your looking for a little softer ride, go with thuren.
Thuren is also focused on offroad performance but is alot cheaper.
As far as control arms go, you dont need them unless you plan on driving aggressively threw whoops and what not. You can always just get some control arms later down the road. Although it is better to get control arms because they articulate alot better than the stockers (they dont bind), the bushings are alot stronger, some control arms are bent for tire clearance and most importantly they push your axle back to center since they are a half inch longer after you lift your truck.
I recommend buying a steering box stabilizer and a trac bar when you loft your truck to avoid death wobble.
(Carli trac bars are identical to thuren trac bars, one might cost more though)
Also the "T-style" steering helps alot with the handling of the truck
