Go to upgrade it again and select 'Restore' instead 'Buy'. This will pull all of the purchases you have made through the AppStore on that Apple ID to this device.
The saved missions will either need to be transferred via email or AirDrop. The next release (4.1) will have a mission sync feature.
The "mme_username" is a place holder for users who had previously manually entered the Access Password. It will work fine the way it is or you can press log out and then log back in. Good question.
