Naval jelly won't work on aluminum; only steel. For removing oxide from aluminum, use any moderately strong alkaline solution. Household ammonia often works fine. I keep a dilute vat of sodium hydroxide (AKA lye) solution around for such things, but that's a bit more hazardous.
You can use naval jelly on chrome, even though the manufacturer advises against it. I've done it many times, with no apparent ill effects. You probably don't want to use it on show-quality chrome, or leave it on for a ridiculous amount of time. But Schwinn parts? I doubt that you'll see any damage.
As for preventing re-rusting: I haven't found any really good solution to that problem yet. Rust is one of those things that we should view as a part of life, I guess. One trick: cover the chrome with automobile polish while the bike is stored, then buff it off before riding. Reapply if it will be stored any length of time.
