What you really need to do is make the chassis more rigid. A rigid chassis will transfer bumps in the road to your springs and dampers. To really get rid of all the rattle, you need a complete overhaul. Coilovers, bushings, sway bars and strut tower bars. Then since your call will be lower, you'll need tension rods at the very least to correct your alignment. I'd also suggest foam injection, since it will really stiffen up the frame of the car.
But that all costs a lot of money.
I'd look at bushings and sway bars first, with strut tower bars and coilovers later. Z's with fully built suspensions ride better than stock Z's because they have very limited chatter.
