Setting up a Dual PC arrangement

I'd like to setup two computers (vista, fsx). Main runs VC and joystick controls. The second machine runs radio and AP panels. The idea being that there isn't a resource drag by running a second screen.
Both computers are already on a gig lan. I need to know what to do next.
I assume I install FSX on both terminals. Should I be installing something like FSUIPC? And then what?
