You could do what WEG did with their Force Powers and have a couple different "categories". Ones that are mental influence on others would be EM/EM/SD, while ones that affected your physical prowess would be SD/SD/EM, and ones that were future seeing would be IN/IN/SD...
One interesting aspect of the Force is the added intuition it gives Jedis. Supposedly, because they could effectively glimpse into the future, it's what gave them the ability to deflect blaster bolts with their lightsaber (otherwise the shot is too fast to know where to move your saber to deflect it). Not sure how that would translate in a combat situation, but it's one of the things that made Jedis very good fighters, and why Jedi vs. Jedi fights tended to last a long time (thinking the Anakin vs. Obiwan fight).
