transfer of power in the forehand

[whatsgood4u]

lately I've been arming ar "muscling" the ball on my forehand. I"ve been trying to get more power from my torso by rotating and kind of "pulling" the racquet around. My question is this, while I know that you're supposed to lay the wrist back i'm not sure about the upper arm and shoulder. Are you suppossed to turn the torso and arm/shoulder in unison or do you turn first and let the entire arm whip around for the shot? (not sure if I worded this right, hope you understand the question)
Ps. if you haven't guessed allready I am trying to simulate the straight arm forehand that roger federer uses.

Yes, the body starts to turn / you push off your outside leg before you start swinging. This is somewhat of an advanced move, however. Make sure you can consistently hit rotating the body / pushing off w/the outside leg / swinging the arm more or less at the same time. Once you can do that, then you can practice delaying the swing a little bit to create a whipping effect.
