Other rusted parts can be relatively easily replaced if you have a bike coop nearby or inexpensively online from somewhere like niagara cycle. The bike has a couple rough spots but with some elbow grease and a bit of learning you'll do just fine.
I would strongly suggest you NOT do this; the bike almost certainly has 27" rims with 40 spokes rear, 32 spokes front.
AFAIK, you can NOT find new 40 spoke rims anymore. You will be better off just taking the rust off with Scotchguard pads. Oil the hub with a light oil like sewing machine oil.
