Hubs, bottom bracket, and headset need to be disassembled, cleaned, and repacked with grease. If the grease is 80s original, it's not really grease anymore. I can walk you through that if you want. You'd have to buy some tools, but bike tool are pretty cheap. If the cables look old, replace them. Brake pads too.

Popukui Nui is the expert here on derusting and restoring frames. She helped me with my 1955 3-speed. I've now derusted and treated 2 frames.
