Back up the iPad to the iCloud, if you haven't already. At least that way, you should be able to restore if you screw up.
Speaking of backup, Apple has introduced a new feature for backups, and its called iCloud. You can set up iCloud, so that all the data on your device is constantly synced to the cloud. Once you want to sync with a new computer, you can provide it with your iCloud ID and password, and all your data will be downloaded to that computer. Its that simple, but as long as your device is running iOS 5.
