The wipe data and factory reset option will wipe the /data partition which includes application data, any apps you've downloaded, pictures, music, messages, and contacts that are not stored on your sd-card. In addition to wiping the /data partition it also wipes the /cache partition which mostly contains your apps temporary files, and other system related temporary files. Your contacts can be backed up to your Google account, messages can be backed up with SMS Backup +
, and for your other data I would recommend taking a look at My Backup
it doesn't require root, if you are rooted Titanium Backup
is a very handy tool for backing up your device.
