The (capton) tape you can do without. It usually stick only one time anyway. Have you paid attention to the four grey plastic clamps on the chassis? They sit right above the eject side of the DVD drive. They should stay in their notches, open side pointing into the machine. The topcase should snap right in. Also have a look at the routing of the hard disk wire and the bluetooth antenna on top of the drive.
