Cyclone II components are more than good. I'd drop the rusty bolts (seat bolt and chainrings) in an oxalic acid solution. Go with a new chain.

Try truing the wheel yourself first. If you can't get it, take it to Peddler's in Henrietta, and ask if Jack can straighten it out for you. He's built and fixed more wheels than 99.99% of people who have worked on wheels.
