First you need to make absolutely certain you've killed that virus, or it may re-infect via one of yout other drives. NOT GOOD.
Try an online virus scanner or a specific removal tool.
Obviously back up your documents, mp3s, photos, and use the files and settings transfer wizard. Once you have absolutely killed the virus, you might consider imaging the drive before you wipe it, just in case there's anything you miss. Acronis Trueimage or recent versions of Ghost will let you restore individual files and folders from an image file.
