Perhaps this thread would be helpful to you. It shows much of my basic method.

IMHO:
Don't bother tuning the propeller to start. Even the airframe doesn't matter all that much to start.
Set it as a constant speed prop with enough reduction gearing to be able to achieve full engine RPM at the airspeed you are testing at.
That will show you what your actual engine performance (HP / Torque) is with just engine parameters.
Adjust the efficiency, torque drag, supercharger to get correct power at full RPM at SL and at altitude.
You can then adjust efficiency to get the proper cruise HP settings at less than full RPM and manifold pressure.
Be careful here because sometimes the numbers won't actually fit together.
I was once trying to tune a Wright R-2600 and found that once I had the correct cruise setting, I could just raise the manifold pressure at the lower RPM and actually get more power than I was getting at full RPM because the effiiciency was so much better at reduced RPM.
After the HP is set properly, you can adjust the propeller variables. If you mess with the propeller first, all the overspeed and lugging issues are going to mask what your engine settings should be giving you.
Just out of curiosity, What aircraft are you working on? (Simpler question than asking about all the engine specs.)
