EDIT:
Keep in mind, every shot will be a little different. For an up hill shot you'll need to use a longer club or hit the ball harder...and a shorter club or hit the ball softer for a down hill shot...its similar to playing into or against the wind. But you'll need to practice all these shots to understand how much power and spin to apply and how much roll or bite you'll get in each situations. Check out the Video Tutorial on "How to use the right club" and the info on "How to hit the ball" over there---->
