Should I prune my tomato plant?

Answer 1

You can "sucker: it for bigger tomatoes. Just above each branch another branch will start to grow. This is called a "sucker" and draws strength away from the branch with the fruit. Pinch them off with your fingers.

You don't have to do this but you will get more and bigger tomatoes if you do.

Answer 2

just the sucker limbs. the ones up to 6 inches off the ground.
