Small bit of advice.
Don't be in a rush to get to end game. It's just not that good.
Play the Jedi knight. Hell, play all the class stories and find out which of the 8 you like best. Class stories are the best the game has to offer so play through those.
Just don't be in some huge rush to get to end game. Play those class stories as end game really isn't worth it and to be honest, everything after those class stories goes down hill pretty fast.
