Simple trick: Place your hands at the bottom of the steering wheel. While watching your mirrors (or, if you must, looking over your shoulder), monitor the trailers' progress. Move your hands in the direction you want the trailer to start turning. It's the initial direction of steering that screws up most people backing a trailer, and this is a quick way to get it right.
As far as how much to cut the wheel, and when to counter the cut, that's just practice, so you'll get there.
