Looking for Deadlift Critique - Video Included

[Deadication]

I've pulled my back twice (once lifting and once playing kickball <-- pathetic) looking to get back to moving a respectable amount of weight off the ground against it's will while maintaining great form to prevent another injury. I've included my most recent pulls (4/18/13)

W/O was
125 x 12 - Touch n Go
175 x 8 - Touch n Go
225 x (1 x 5) - Reset each pull
275 x (1 x 3) - Reset each pull
305 x 1 (Video1)
325 x 1 (Video2)

In hindsight I wish I had used lighter shorts in contrast to the back-round so it would be easier to analyze hip and knee movement throughout the lift.

Thanks for taking a look, any help is much appreciated and +rep'd
