A lot of people have found that stiffer shocks do help sharpen the ride and control, and of course, street tires, rather than AT's, are better on the road.
Timbren bumpstops have also been used successfully, as they are longer, but softer...so that the truck leans on them sooner/gets some suspension support in turns, etc., w/o jarring stop impact hard compounds give.
You could get a spare set of tires for street duty/play duty...and swap them on as needed.
