Stickers are going to leave marks worse than scratches if you ever try to remove them. Many people try to use Brasso to polish their iPods and some claim that is a miracle worker, others say that it didn't work. I tried this and found it to be somewhere in the middle. Brasso will probably not hurt your iPod, but you should take up any button openings etc before you attempt to use it on your high priced investment. They also sell things like Ice Creme and iPod Cleaner online, but these are expensive solutions to the problem. Good luck, and contact me for more Brasso tips.
