If you are looking for good assistance exercises, there are many...wide stance good mornings being my favorite.
You may also want to try box squats and speed squats (on a box). This can help with form, and help with generating speed and power from the hole.
I second the Good mornings, they help me out alot. I also agree with the box squats, I have gained a ton from using chains, box or both using the box as a touch and go. Pistols are another good one. Also GHR's, even though I am terrible at them!
