Most engine rebuild shops have a glass-bead blasting cabinet. As for restoring wheels yourself, try Nevr-Dull in a can (wadding) for the outer rim. It's a lot of elbow-grease but the results are immediate. Oh, and use adequate ventilation when you work with Nevr-Dull or you'll get quite a buzz. You can gently wire brush the spokes (GENTLY) to knock off any corrosion (steel wool works too) and paint them silver or ____? If the outer wheel (not the spoke area) is in good shape and needs no repair work I'd recommend skipping the cost of blasting and just clean the wheels up yourself.

As for buying the 15x4 mags, I guess it depends on what you want to do--what look you're trying to achieve. I'd assume that the price of the mags is somewhat high but AKH does nice work, in my experience anyway. Also, 4" wheels on a heavy car make decent handling a thing of the past. If you're going for the drag-race look then you're okay, just don't expect to go rat-racing up some canyon road, especially with something like a big-block Chevy up front. In my humble opinion, of course!
