To save you the headache, start here: Bump Stops

Lots of good posts with pics of what needs to be done. I would HIGHLY recommend you start by cutting your bump stops, THEN proceed to shocks only if the ride quality is still too harsh for your tastes. Cutting the bump stops can be done with any common saw blade and for only the cost of your time. Shocks can run from $200 on up depending on the brand, so IMHO start with the cheap fix and work your way up.
