I use wraps to help my wrists as no amount of shoulder stretching seems to help. Dislocates my help you though so don't stop just yet.
Chalk your upper back to stop the bar slipping. That extra grip will make you more stable.
Think consciously about using more back and hips in the lift.
Take your time when setting up more than normal. Make sure the bar is in the right place, that it's centred and balanced. Walk out slowly and set your feet and hold still before starting your set.
Lastly, and this top applies to all multi rep sets, think of your set not as 10 rep's but as 10 individual singles. They should all be identical and your form should be the same on each one. Too many get sloppy as they try to rep' too fast.
Hope that helps!
