Wlan networks in general are mainly about channel reuse. If you manage to do that the network will be ok, otherwise not. But generally I'm not a fan of beamflex for HD. It's not the right tool for the job in most cases if you ask me. Depends on what the circumstances are but For HD I would think of using 7372E with external antennas to limit cell sizes. Then comes the optimization of network parameters.
The questions you are posting make me think you would need to consult a professional to help you with this project. Ruckus is great, don't get me wrong, but someone that knows what they are doing is worth a 1000 support calls.
