There's an easy to confirm to confirm that the wheel is properly dished on center. It'll tell you whether the problem is wheel or frame related.
1- Stand the wheel straight up on level ground, open the QR (or loosen axle nuts) and let the wheel settle naturally in place. If you have horizontal dropouts, center it in the chainstays by eye, and note the position in the slots.
2- measure from the seatstays to the rim on both sides.
3- remove the wheel and re-install with the cassette on the left, in the same position following the same. method as earlier, and re-measure from the seatstays.
If the seatstay distance is unchanged (or slightly changed) the error is in the frame
If the seatstay distance is about the same, but reversed than the wheel is dished improperly
If the seatstay distance changes to new numbers entirely, it's either both, or you were inconsistent and should try again.
Note it's critical that the wheel is mounted on the ground with the weight of the bike on the axle, so it rests firmly on the top of the dropout slot, otherwise you have no true reference for it's position. Many cases of suspected mis-aligned frames are simply wheels that are canted in the dropouts, ie. touching the top of the right, and bottom of the left.
As for the rust, use an automotive cleaner wax or one step wax which has a bit of mild abrasive to clean it up and seal the finish. You might not get the spots out without dulling the finish, so settle for whatever looks good. Keeping it waxed will slow further rusting, possibly for your lifetime. If you want to do a more thorough job, you can use auto wax polishing compound, then wax, but read the instructions so you don't dull the paint.
