Question for the piston-heads!

G'day guys,
I've been flying the heavy metal for a long time now and I wanted to get into the pistons again for some touring.
Is there are good site which explains flying the pistons - climb/cruise speeds and alts, when to pull all those mixture knobs, cowl flaps, etc? I don't understand any of that!
I'd especially like to do more Baron and DC-3 flying if that helps!
Cheers
Stew
