I think you got some loaded questions there.
Best power/speed is a combination of factors involving engine, = prop,=20 airframe, weight, ego, wallet etc.
 
For maximum TO/ cruize etc. same applies but your nerves, wallet = &=20 cooling are probably the limiting factors.
 
I have a quadrant with 2 levers, 1 marked noise, 1 rpm, I find it = best to=20 have noise set at loud for takeoff & rpm at fast. For cruize noise = at not so=20 loud & rpm at slow. Landing, noise at less, rpm fast.
 
Seriously, You'll work out your best settings when flying off your = initial=20 hours.
