Answer 1

Downgrading an iOS is not supported by Apple but that would not bring the items back anyway.
What photos are you talking about?  If they were synced to the iPod then you will have to get them from the computer from which they were synced.  If the photos were taken by or saved to the iPod then they should be in the backup.  The same with notes.
One the computr go to iTunes>Preferences>Devices and look at the da and time of the iPod backup.  If it corresponds to before the update was performed or at the beginning of the update then the itmes should be in the backup.  Restore theiPod from backup.  Make sure thatyou have auto syning turned off other wise when ou connect the iPod to the computer iTunes will backup the iPod which does not have the items and delete the old backup.  To turn off, go to iTunes>Preferences>Devices and check the box that say Prevent iPods.... syncing.
