If you can't remember the Passcode, you need to restore the device from the computer it was last synced with.
Follow the instructions for putting the device in recovery mode >
"If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Follow the instructions for placing the device in recovery mode here > iOS: Unable to update or restore
iTunes purchases can be re downloaded for free using the same Apple ID that was used for the original purchases > Downloading past purchases from the App Store, iBookstore, and iTunes Store
Resetting is the only solution. He will lose everything unless it was recently synced with iTunes so that there is a restorable backup.
what i usually do is
plug into iTunes
right click the ipod and make a backup
put it in restore mode
restore the IOS
restore from backup from iTunes
all your stuff is there and it would ask you to enter a new passcode
one thing about manuely adding the apps is it wont store your save games, only in backups and iCloud it will
