I've been nursing vintage lightweights for about three years now - it is virtually second nature to me. (Though most of the fellows have been doing so here for many more years then I have though - I'm the rookie when it comes down to seniority).

Mountain Home, Arkansas? Anyone here near that would be willing to help Dave out?

Look for a decent pair of 700C wheels. Need not be new or fancy - a pair of used, straight, and un-cracked aluminum rims with stainless spokes would do you well. If you can locate any hole-in-the-wall (preferably - more likely to have older parts at good prices) bike shop in your area, visit them and see what you can find.

An adequate rear derailer would have been the Campagnolo Nuovo Record or Super Record, but the former's penchant for fiddly first-time adjustment would probably drive you nuts. Super Record would do nice, but it is usually pricey. If you want to stay on budget, seek an older, slant-parallelogram derailer.

Suitable cranksets include Campagnolo (same as what you have, but the stock model), Mavic, Ofmega, Galli, some older Shimano, etc.

Use some Flitz metal polish (if not Flitz, Blue Magic or Never Dull works well) on the aluminum lugs to shine them out. I've never fiddled with early carbon fiber, so I don't know exactly what would be suitable for the tubing.
