Skippy, I endorse all said before.I fly an Arrow 4 so similar to a "2". Once you fly it for an hour or so it will all fall into place - it is really not a major problem. It will all seem a little busy on and just after take off for a while until you get used to it, then 2nd nature.
re the power settings :- there are many combinations and on mine there is a easy to interpret table attached to the pilots sun visor - you want 65% power at 4000'? Look at the visor and it will give you a choice of RPM / MP settings - eg 2300rpm / 23" or 2400 rpm / 22.5" etc etc (these are not actual figures - just illustrative).
You will also see that the fuel flow meter is marked with white lines for the range of flows to be set (with the mixture lever) for each of 55%, 65% and 75% power. It is all there in front of you so you do not have to keep looking at or memorising the handbook.
Hope this helps,
