try to keep your right leg more bent in your back swing also
instead of slowing it down, try to squat into your backswing...normally the feeling of coming up and out of your swing is what is straightening your leg, do the opposite and have the sensation of squatting into your take away
Which way? How do I fix that? You mean coming over the top by 10*? Definitely have slicing issues...
Negative is left of a square plane, positive is right of it. You fix it by not swinging across the ball.
