The age-old "hand part of ball"

I understand for both NBA and NCAA men's basketball, the rule is that "Contact which occurs on the hand of the offensive player, while that hand is in contact with the ball, is legal."

Two questions:

1) Does this rule apply when someone is shooting?

2) If it does apply, what if the shooter is blocked from behind by the defender pushing the back of his hand to move the ball?

Thanks much
