also if i want to lower my front end, do i have to compress the spring or extend it?

The larger of the 2 sizes work best. Also you would need to extend or loosen the spring preload to lower the ride height. Don't go below 26" from the ground through the wheel center to the fender lip. It will mess up your camber setting too much.
