Go to Bikepedia.com and search under the "Bikes" section of that site. Your picture is sort of dark so it's hard to see any distinguishing decals.
As for the chain, you'll need a chain breaker, removal tool that you can buy at your bike shop along with a new chain. Determine the length of the replacement chain by using the old chain as your template. Do not try to ride the bike with that rusted chain, you'll ruin the cassette. I wouldn't disassemble the bike until I replaced the chain and see how it rides. But that's your call.
