Well, one interesting r/l thing you might try is setting a trigger phrase to freeze your sub on the spot, or make them experience being tied down. Those actually work - I can tell you that from experience. You can also simulate the sensation of being spanked, which is pretty cool because it stings like hell and won't mark you up.

As far as stories go, I'm not an expert (my bf is) but I would recommend Wiseguy from mcstories.com specifically, since his stories are pretty solidly realistic. None of the ray-gun slavery stuff.

And "teach" you? Do you mean r/l teach?
