Wouldn't it have been a bit easier to just give us a link? :)

Sure but I don't mind posting them.

I know other games do this, but if I complete the game on say, Sith Lord, with that automatically unlock the achievements for the lower difficulty levels?

You know I don't know that is a great question.

I only ask because, judging from the demo, I will likely start off on Sith Lord. I don't know if it's possible to unlock Sith Master in the demo.

It very possiably could be.I know in Halo 3 if you beat it on Legendary then you would unlock everthing below it.
