The heavier the spring, the stiffer the suspension. Lower pressure springs will give you quicker weight transfer, but will bottom out faster when street driving.
Exactly...The spring has to be compressed to store the energy...
True. Lighter springs will have to be compressed more to support a given amount of weight at a given ride height. This makes the suspension more "lively", stores energy in the spring and helps with separation. A good DA shock is needed to control the suspension when going this route, front or rear.
