Question Constant speed props

I have never flown an aircraft with a variable pitch prop but am going to learn at Easter. However, I am having problems understanding the operation of the prop lever and throtle.

I think I have a clear picture of engine managment in flight, ie rev up and throttle back. But as I understand it, on the ground, do you taxy around with the blue prop lever full forward at 2400 rpm ('ish) and the throttle right back or does having the throttle right back mean it reaches the fine stop and thus the rpm decreases?

On a Piper Arrow, just before engine start up, is the prop lever full forward and the throttle open a bit. You crank the engine and move the mixture to rich when it starts. then in the checklist, it says adjust power for 1000rpm and then warm up at 1400 rpm. forstly this is unclear because there is no 'power' lever and secondly how do you adjust the rpm up to 1400 rpm if the prop leveris slrady full forward.

I hope this isn't too full of waffle, and would be very grateful if anyone could shed some light on this subject and make it a bit clearer for me. Thanks.

Also, if anyone flies an arrow II, do you have the cruise speeds at 55, 65 and 75% powers handy? Ta
