Brake/gear lever positioning

I'm getting into this mountain biking and have seen many recommendations to move the brake levers in-board for more powerful braking. I've moved mine in a bit, but do you guys think I should move them some more?

My gear levers are getting pushed quite far down the bars, so can I swap the gear and brake levers around, so the gears are nearer the bar grips? Do I need to adjust anything with regards the cables (or any other part of the set up), or can I just move the levers without worrying about anything else?

Sorry for the rookie questions, but I'm learning!
