Q: Trying to restore from back up and it is asking for password.

IF you don't remember the password for the backup then you cannot restore from that backup.  In iTunes make sure you do not have a password set for backup and delete the backup you cannot use and create a new backup

Go to iTunes on your computer and select the phone form the left column then in the Backup section make sure the box called encrypt backup is not ticked

All I could find for you was iOS: Troubleshooting encrypted backups and http://hints.binaryage.com/itunes-asks-for-a-password-to-unlock-a-backup-that-yo u-never-set/

The iCloud backup saves photos and videos in the camera roll.  If the backup you restored from did not restore photos and videos to the phone then the backup did not contain them.  Check to see if you have more than one backup available.  IF so you might restore from that.  remember you cannot select what data from a backup you want to restore - it is all or nothing.  So if you restore from an older backup then that is what you will end up with.
