Your stat bonuses continue to go up passed 20. Although I found that there is no real use for intelegence passed the initial bonuse it gives you at character creation. Dont worry about Charisma unless your going to persuade throug the hole game to make some coin! (they say that with a higher charisma its easyer to comand yor troops, but with a 16 chr they where still doing whatever they wanted to do when I wasnt selected on them)
Strenght is good if you just want to beat them fast
Wisdom if you want to be a force user primaraly
Dex is good for distant weapons and AC (I like AC) especialy of you are running around in robes...if you plan on using the heavy armor dont bother with dex
Constitution, if you want lots of HPs go for this one, Best thing if your going to be a force user make yourself a soldier first to give yourself some HPs

Iv run through the game 2 times....going through a 3rd just becouse Im bored. I picked a Scout first (becouse of the implant) not that I couldnt get them with the other classes, but these ones are free. and they get a desent number of skill point to start. Treat Injury is a must, I didnt have it up very high on my last toon and I found myself, when i ran out of force points, over using my heal button and not hitting anything for minuts at a time.
I then went with the gardian class Jedi...I dont realy solo, I just want to BASH!...pumped up my conducting, and toughness as well as one handed melee...thats right ONE HANDED...this was mostly for the ac bonuse, as well as a flury and I walked through the bad guys.
But hey! play what you like..the game does give variaty based what your playing style is.
