For fun I have decided to level a Sith Warrior and go full Light Side. Is there a guide or website I can refer to make the correct conversation choices?

I am looking to start leveling a Jedi Knight Sentinel. Is there a certain order I should be using abilities or just use whatever is available? I can never seem to be able to use still without having lots cooldowns to wait on.

Thanks for the info.

I currently have a level 10 Trooper and looking to roll a Sith Class. Which class do you suggest for me? I was looking at a Sith Warrior but was not sure how hard it was to play/

I know there is not a "rotation" you can 100% stick with while leveling but are there any suggestion what I should be using? I am currently level 10 and decided to go with a commando spec.
