Sold my Off Road 16s. Mod Money?

Sweet. I posted an ad to sell my factory 16" off road rims, had people kicking my door in for them. Sold them this morning! Biggest thing is it was taking up too much room in my basement ( I like my toys ) I still have a black/chrome front grille for sale. What mods should I do next? Maybe suspension? I see a lot of people on here have the Bilsteins. Is there much of a difference in ride? Mine is more of a street truck hence the 18" wheels, so something that's good on pavement. Thanks for any input or ideas.

P.S. One more thing I want to get rid of as far as aesthetics go. The lower fascia. I got the black grille, painted black bumper (operation remove all chrome) now it's just that horrid plastic fascia that houses the fog lights and lower rad. I'm sure there are some sexy aftermarket ones. Also, LED map lights. I camp a lot, and having interior lamps that don't hog the battery would be nice.
