What a great addition to the D20 system, I was so impressed when I first noted that Hit Points had gone in favour of Wounds and Vitality. Then upon reading further I was so disappointed to discover that Vitality was just another way to soak up damage, in essence its still Hit Points but by another name.

Rule Revision: Wounds remain like Hit Points (i.e. they soak up damage), Vitality on the other hand does not, it forms a reservoir of inner strength that a hero can draw upon to perform heroics (it also fuels force powers as well). Vitality may be expended voluntarily at the beginning of a combat round to give the hero bonus points to any action (most notably defence, but also attack or even saving throws), it's simply a way to represent the heroes focus and determination.

This rules modification is open to abuse, it is intended to give the game a more heroic feel, if you feel that players are abusing this rule to kill of your favourite baddies then just remember that expending Vitality to gain bonuses can be done by anyone with a hero class. At the time of writing this I have not felt the need to place a limit on the number of points that can be spent per round but you may wish to impose a limit equal to twice the characters level (just as an example) and you permit new feats that permit the hero to expend more vitality per round.

Naturally when the hero is out of Vitality he's going to be out of luck. In my games I have found that not knowing what is coming next tends to stop players spending all their characters Vitality in a single burst… and remember when you run out of Vitality the normal rules apply (Star Wars Core Rulebook p132).

Under normal circumstances most creatures, aliens and what have you get a number of Wounds equal to their Constitution Stat. That all seams fair and wonderful until you consider that something the size of a Tatooine Sand-Fly is going to be a lot easier to kill, in terms of damage it can take, than say a Bantha.

Rule Revision: Given that Wounds represent a certain amount of structural integrity as it were, it seams reasonable to me that large creatures should have more than smaller creatures. But how can this be modelled? Simple, for medium size creatures (most characters and races in Star Wars) everything works just as it always has. For each size class smaller than medium divide the characters Wounds by 2 (rounding up), or of each size class larger than medium double them.
