this is sort of a cheap answer but the rudder required is whatever becomes necessary to keep the ball (on the turn/slip indicator) centered. At this stage of your flight training you should be referencing this instrument quite often, and over time you'll have to use it less and less.

You'll come to find that there are no absolutes in aviation. In many high powered piston airplanes you need no left rudder in a left turn... you need merely a reduction in right rudder force. This is an excellent example of the airplanes inherent left turning tendency!

So... whatever it takes!

As for stalls, always pick up the low wing with the rudders. If the left wing drops, kick right rudder (this will increase the speed of the left wing allowing it to roll back to level).

Ask your instructor to demonstrate a 'falling leaf'. This is a maneuver where the aircraft is kept in a stalled condition so the student has a chance to control the airplane only by rudder pressure. The yoke should be held full aft and not moved (the yoke does not control the wings in a stall!!)

Hope some of this information helps. Good luck
