You are given a two shot penalty in stroke play, or loss of hole in matchplay.
stoke penalty
Under normal circumstances, with your ball in the sand, if you touch the sand with your club and are not in the process of making a stoke (the downward motion of the club with the intention of hitting the ball) you incur a penalty for testing the sand. But since Tiger's ball was NOT in the sand when his club hit the sand he was not penalized. I think...please correct me if I'm wrong.
In the case of a place such as a penalty kick the ball can sit in a small plastic cradle or pile of sand.
After ou step out of a sand trap you should Use your club and gently scrape all sand back into the sand trap. Then you should use the rake and spread the sand evenly out.
No! A stone is a loose impediment. A sand trap is a hazzard. You cannot remove a stone from a hazzard if the stone and ball are in the same hazzard. Penalty...one stroke.

This is known as casual water. You are allowed to take relief, you do so as follows, drop the ball anywhere in the bunker, no nearer the hole. You do so unless the course manager has designated the bunker Ground Under Repair, in which case you get a free drop out of the bunker.
Tap the bottoms of your shoes with your club so the sand goes back in the bunker and then rake the bunker with the rake provided.
