My wife uses the newer Look KeO cleats which she says are easier to get in and out of. I've been using Speedplay Zeros for a couple of years and find the in and out much better, but with a different feel.
As for stopping, we both unclip our left. To start, we bring the right foot up and then push off on the count of three. This works great for us and makes my wife comfortable at stops. She has stayed clipped in a few times, but doesn't care to do so.
