Looks like a sweet deal to me. Check Niagara Cycle Works for tires, cables and parts. They have the cheapest prices around. The Schwinn Racer actually looks pretty neat to me. If those are Bluemels fenders (in good shape)...wow! If these bikes weren't so easy to work on I would say you have some nice winter projects. You should, however, be able knock them out by fall. The scrap metal yard will probably give you a few bucks for the junkers. Looks to me like you did well.
