Second paragraph was squats. I think one thing about knees in front of toes is that you have a tendency to end up pushing with the front of your feet and shifting the weight instead of staying on the heels and outside of feet.
Glight brought up a good point....for deads, take a deep breath right before you lift and hold it. This will help protect your spine.
