There's two ways that I would recommend, both are going to cost you between $350 and $600. Upwards from that if you want to get something brand new rather than used, or if you get ripped off, etc.

First solution, for the regular average every-day driver:
KYB AGX Shocks. They're adjustable (4 ways I think) and will suit your needs very well, they're great shocks and not overly expensive and to match those go with a spring of your choice, some say Eibach some say H&R Sport/Race, etc. etc. Its your choice really, depending on what kind of height and ride quality you want. Of course, you could always go with some sleeve coilovers (Ground Controls) to match those shocks and that'd be even better.

My perferred choice, and some wont agree; Koni Yellow Shocks w/ Ground Control Coilovers. It's not a 100% true coilover setup, but its an excellent setup and not going to destroy you in the budget. They wont rust, since they're anodized and they're going to give you the adjustment you want when you want it for height, and the Koni's are infinitely adjustable for ride quality. (Mainly compression).
