Damn, you want to repaint THAT? Other than the scrapes, the blue clearcoat looks wicked. If anything, I'd strip it to chrome and be done with it.

As for parts, I'd start off with stripping down the bike, getting the wheels trued and tensioned, rebuilding the hubs, BB, and headset, rustporoofing the inside, getting new brake pads, cables, and tires, and then think about new components.

Handbuilt wheels are pricey, as are campy groups, unless you have a buddy with old parts he's just giving away. Work with what you've got, then decide what you need
