The headlights can be changed without moving anything....well, you'll have to move the winshield washer fluid thing out of the way, but the battery you shouldn't have to move...unless you're going for the high beams. As for the rust.....heh, all 4th gens have that it seems....as to cost to get it removed, I havn't the slightest, my brother did a quick job on mine a year ago, but it came back..... (he told me he didn't cut out enough metal for it to have any permenant effect - he was right). Anyhow, the bumpers can easily be painted cheaply at a collision repair center...$100 for each probably.

Get out the phone book, most places will give you an accurate estimate for that kind of stuff! GOOD LUCK AND WELCOME!
