From the enterprise manager you can restore the backup to the newly created database.
In MSSQL 2000
-Right click the new database
    -All tasks > Restore Database
        -Options Tab: [v] Force restore over existing database
        -General Tab: (o) From Device
                               [Select Devices]
                               [Add]
                               Select the backup
                               [OK]
          -[OK]

User:
In my case the user is in the backup, but I use windows authentication.
I think for sql server auth. you would have to recreate the user
It's better to create a new user, since the dbo has all the rights, even to delete other databases on te server.
If you are unsure about this, I would try it beforehand on a test machine.

You are right it's easier to move that way but it's difficult to do a scheduled backup.

Yes you can, the only thing is that you have to set "Force restore over existing database"
Did this as a test for my post this morning
