My opinion, leave the 1 pump in it and tune the engine. I run a 1/2 pump on a stack injected small block. Leave the high speed in the tool box until you get the system tuned to the point of needing it.
Injection is pretty straight forward, but there is no way anyone here can get you on a dead nuts setup, it will still need to be tuned regardless.
There are plenty of books on injection, the one I believe is the best is HRE Fuel Injection Basics. There is also the option of sending the system to someone like Spud Miller or Ralph Gorr with your specs and having them set it up for you.
