I'm in complete agreement with Steve; can't do much about chips but touch up. Prevention is the best defense....
...my 2006 Black IS 250 suffered the same problems, especially during the winter, with constant rock-salt & gravel dings on my hood & front end...
...unfortunetely (or fortunately), that car was totaled in June in a front end collision, and I've replaced it with a 2008 copy, BUT, installed a clear bra right after purchase, per my own observations and experience, as well as Steve's sugggestion...
...so far, it has worked out great, although is has not been given the acid test (no significant snow fall, and thus, no significnat salt, sand, etc, here in DC)....
But so far, no dings, and no touch up paint, and the car looks much better than my previous iteration....
SO,....I would recommend a clear bra if highway travel is your norm; it is minimally conspicuous, but the benefits outweigh the downsides...
Just some thoughts...
Cheers,
Mike

All you can do is touch them up with touchup paint. I'd have a clearbra put on the car.
As for the scratches on the doors, can you describe them a little better? Can you feel them with your fingernail?
