I wont comment on the squats, since most posters gave good advice, but watch yourself in the deadlift. Ask yourself, does your body move in one fluid motion? If you watch closely, you see that your butt comes straight up and you basically negate anything you would gain from your initial squat and end up using much of your back. Your body should move all together as one.
Throw your pride to the curb on weight. Today I did hang cleans with the bar because my form was off. Take your time, OP, and I'm glad you are posting these videos!
