Hopper 1 and Hopper 2s are three tuner boxes. The Hopper 3 has 16 tuners. What exactly are you having problems with since you can record and watch more channels then you know what to do with?
The Joey is a simple slave box to the Hopper which has all the tuners. With either box, you can watch and record multiple channels. You don't need any other tuners.
The Wally doesn't integrate with the Hopper, it is a standalone unit. So I'm really confused as to what you are trying to do.
