The only way to prevent access to an iPod Touch that was stolen is if you have a passcode on it.
When you unlock a passcode that has been forgotten on your iPod Touch, all of your songs will unfortanetly be deleted, and you will have to put all of them back on. But if you are CHANGING your passcode, off of the settings button on your iPod Touch, nothing will happen to your current memory.
