After watching the video I can say two things:
1. Try adjusting your bindings back a bit. As the others said, your toe overhang is bigger than the heel side. That's not dramatic but it's better if you have them equal.
2. The pushing up problem with the boot might be because the boots are very wide for the bindings. I've seen that same thing with a pair of Burton boots and Ride Capo bindings. That is not a big problem though as you will push your boot down with your body weight when strapped in anyway. All that could happen is that you have a bit more wear. So don't worry about that too much.
