Rich.
I think you got some loaded questions there.
Best power/speed is a combination of factors involving engine, prop,
airframe, weight, ego, wallet etc.

For maximum TO/ cruize etc. same applies but your nerves, wallet &
cooling are probably the limiting factors.

I have a quadrant with 2 levers, 1 marked noise, 1 rpm, I find it best to
have noise set at loud for takeoff & rpm at fast. For cruize noise at not
so loud & rpm at slow. Landing, noise at less, rpm fast.

Seriously, You'll work out your best settings when flying off your initial
hours.
