I have a Sith Marauder that I was running full light side. I picked my first Dark Side option on Alderaan today and it's been bugging me so much to think about that I'm considering resetting class quests on the planet. Are there any benefits to going full light/dark side or will it not make a difference anyways?

I really don't enjoy playing any of the current healing classes, I'd prefer to stick to tanking and dps. What tank/dps can make the largest impact in a warzone?

I'm the type of person that knows I have trouble sticking on one toon, but I am determined to do it on this game. The only problem with this so far has been the fact that I am unable to choose between my Marauder and Powertech because I lack knowledge of high end PvP. So my question is this: TL;DR - What is the most useful and effective PvP class at maximum level PvP? I need to know because I plan to enter ranked combat once they add it.

You're too low level. You have apparently skipped quite a few quests. I am about to leave Balmorra and I'm already level 22 on my powertech. Questing on a BH is easy, just blow through them all.

Got to enjoy a fast learner that isn't a whiner. With the mentality of accepting challenge and hard work this person will go far.

Are you by any chance Lopez from Arenajunkies? If so I'm happy to see that players such as yourself transferred over. I don't believe that the brackets need to split like in WoW, every 5-10 levels, but I do believe that there needs to be some separation. Having a level 10 fight a level 50 is ridiculous, especially considering the difference that talent specializations and late-game abilities make.
