Your squats look basically okay, except for the toes you know about. That problem, by the way, is easily fixed with shoes that don't squish under your heels. If your heels collapse, the place you'll go to is your toes. The thing that makes them heavy is the slight tendency to raise your chest instead of following through with hip drive. When your chest comes up -- when your back angle becomes more vertical -- your knees come forward a little and the hamstring slack kills your PC power.
The press problem you describe goes away if you quit assuming that every press must start from the bar on your shoulders. If you are going to have vertical forearms and if your forearms are relatively longer than your upper arms, the bar will only sit on your shoulders if you let it roll off your hand onto your fingers. You don't have to do this; just let it float a little.
If you want to post your barbell row, go ahead. What the hell.
