Could you explain what you're dissatisfied about more clearly? From what I see, it seems you don't think the rules as stated represent the abilities of the movie characters well enough. I think this is interesting, because the designers changed a lot of rules from the initial release of the core book to fit in better with what we've seen so far in the original trilogy and the prequels.
Check the errata, and look at the revised core book. The revision did a lot to make the use of the force more congruent with what we can see in the movies. For instance, deflection of blaster bolts is now not a feat, but a class ability of both Jedi classes. All three force classes receive more force based feats and abilities, and many of the force feats were changed. The skill descriptions were cleaned up, and explained much better, not to mention more thoroughly. For instance, the Move Object skill now explains how to deal with people using it offensively, picking other people up, picking yourself up (a feat, now) and how far you can move objects in one round.
As much as it sucks, having to buy a new book, I really prefer the revised corebook to the original. Armor has been changed, so now people might actually wear it. The Martial Arts feat has a tree attached to it, as it should. There are +2/+2 feats for Force skills now, so force users don’t need to stop at Skill Emphasis. I really do think it’s worth the investment to switch to the new rules system.
Now, as for new force rules, if you still want to change the rules… I don’t know off hand where anyone has published any, but your idea of using a Force Point system not unlike 2nd edition D&D’s Psionic Strength Points is interesting. Limiting Force use was a good idea, as in the one d6 Star Wars game I played in, the use of the Force got way out of hand. However, linking Force use to Vitality was an interesting way to limit it’s combat potential, and you might not want to overlook such a decision. I played a Force Adept Telekinesis prodigy, and in the end he was fighting better using move object than with his own body. If spending vitality didn’t have such an impact on combat, using the force in this way might have become even more unbalanced (as it was it was a stretch to keep this from getting crazy). It’s always up to you, but this rule was put in place for a good reason, and to good effect.
Hope I’ve been helpful and not simply longwinded.
