Did you update the firmware justinisham? If so, then plugging it into the computer will merely charge it (as you've noticed) but until you can find a power adaptor, it won't let you go any further. It needs to be given a surge of power from the adaptor to properly reset before you can re-sync your iPod. Can you borrow someone else's adaptor? Can you go to an Apple Store and get them to let you use one for a second. It won't take long, it's a matter of seconds.
Just out of interest, what made you update the firmware (use iPod Software Updater)? Were there other problems with it beforehand?
