Oh yeah, as far as what part of the fist to hit with, my sifu told me in one of my first classes that we train to hit with the bottom three knuckles, but that as you progress you hit with the bottom two and eventually with the pinky knuckle only if possible. My sigung(grandteacher) has told me the same thing. If you have any questions or concerns with that I suggest you try the variations on someone and ask them which hurts more. If you don't train the vertical punch regularly please be careful because you can tweak your wrist.
