I have a 92 as well, the headlight should be no problem at all. As long as it is the driver's side. To change my passenger side headlight bulb I had to remove the battery and coolant resevior. As far as the power locks, my motor died and it was always unlocked so that cost me about $180. As long as yours locks and unlocks I wouldn't worry about it. I've also got a little cancer under my left rear wheelwell. Its best to sand it down as soon as possible and replace the rubber stripping on the wheelwell. Moisture gets trapped in there.
