Not sure about the PQ issues you are seeing. The TV likely needs calibration or other settings changed. As for the Hopper/Joey swap, as long as all coax is RG-6, you can swap the receivers, as long as you swap the connections at the node.
Hopper goes on the HOST port and Joey goes on the CLIENT port. Hopper does have slightly better trick play and you would also gain PiP on the big screen.
As for connecting the Hopper to the Internet, that can be accomplished with a wireless adapter if your dad had a wireless AP.
