As already said, your rear brake should be strong enough to hold the bike on a hill. There is a fairly steep hill in the parking lot at work, and I managed to hold the bike with the rear brake and kill the engine. If you have the coordination, it may be easier to start on a hill if you hold the bike on the front brake, using 1 or 2 fingers which allows you to have both feet down and still control the throttle.
As for right turns, what they taught us in the training that I did was to put your right foot down, left foot up, turn the handlebars full lock to the right, lean a little to the right and when ready look where you want to go, roll on the throttle and away you go. Everyone in the class was able to make right and left hand turns from a stop in half a lane using this technique.
Good luck and happy riding!
