I'd also mention:
Pretty much all the character classes are changed so that they get some kind of class ability each level. The amount of defence bonus at 1st level is reduced. (I think all the improvements were great except for the noble, which was better before).
The reputation rules are changed
Changed and new prestige classes (including some Jedi prestige classes)
Some new feats, some changed Jedi skill/feats.
Armour now gives DR instead of adding to defence
Completely revised starship rules
You die more easily - the DC Fort save to be just alive when you run out of wounds has been replaced by a more D&D like just die when you run out of wounds (a retrograde step IMO)
The knockback combat action has disappeared.
Attacks of Opportunity introduced into combat
Quite a wholesale lot of changes.
Cheers
