B-ran - you have a few choices on your problem.
1) if you would like to keep your stock steelies and want to get the wheel covers then you can find them on google.
2) if you want to change your wheels from OEM steels to aftermarket rims, then I would suggest checking out:
The Tire Rack - Your performance experts for tires and wheels
I seriously doubt you're going to find a better deal than tirerack (NEW).
If you don't mind used rims, then I would really suggest checking out:
craigslist: san francisco bay area classifieds for jobs, apartments, personals, for sale, services, community, and events (look up your city and it will listed under "Auto Parts")
3) If you do go with #2 and are worried about the drums in the back, there are kits out on the market that you can purchase that will change from OEM drums to aftermarket rotors. Check out eBay for rotors, they have them for your year.
Hope that helps, good luck!
