Bryan,
Margaret is right about all of the LS products requiring effort. There is no Matrix-style download in any of the courses. Although maybe that's what they're shooting for with the Fast Finish...
Go through each one once and decide where you want to focus your efforts. If you scatter your energies in search of that elusive mega-brain, you limit your results on all of them. After listening to PR and GC, follow your intuition about which one to work with first. Maybe it's as simple as going with the one that seems most fun (gets you the most energized, seems less imposing, whatever). If you're having fun, you'll find the time. Perhaps one will provide the key that unlocks the other. They certainly complement each other.
Personally, I would spend the time on GC first, but that's just me. It is more focused on strengthening the conscious/unconscious connection upon which PR relies (and the Direct Learning work you do just may lay the groundwork for later PR success).
