I guess this will all sound pretty generic, but here goes. Clean and wax the paint, being careful to avoid areas with decals or screening. Chrome polish on the chrome. Ride it around a bit. If anything feels stiff or gummed up, take it apart, clean it with a degreaser or wd-40 or similar. Rinse parts well, regrease them . Bearing grease from a bike shop is probably best. I use Moly grease like for car wheel bearings. White lithium grease is good too. Some people will tell you that automotive bearing grease gets sticky after a while, but I've had it in my 55 Schwinn for over 3 years now and it is still good, and it is my most frequently ridden. People need to be taking their bikes apart for maintenance more often than that anyway. It's all pretty basic, and there are more detailed threads on this site if you look for them. But the main thing is, treat paint like paint, treat chrome like chrome, treat moving parts like moving parts.
