go to monroe sensa trac shocks and buy some used stock coils, so they are already worn in... That should be plush enough for you... Oh and try and run just a little less air in your tires.. Should help you feel less bumps.. I run 30 all around.

Hope this helps... Oh and I have to agree though, you bought a vehicle built on a truck chassis... youre gonna get a truck like ride, but my suggestions may sound weird but they will help you accomplish the plush drive you ar ehoping for.. The bilsteins are gonna stiffen your ride up even more and you dont want that.
