1) Pitching. 30 yards and in is what I have in my yard and I practice shots almost every day. It's already paying off, but I want to get better at them and get up and down more times than I don't.
2) More on plane backswing. I was way too steep last year and recently have got a bit too flat on my backswing. I'm practicing backswings in a mirror at home and the feeling of straight back is getting me into a good position at the top.
3) Not getting too tense on the way back and not trying to kill the ball on the way through. I believe these two are related.
