Glad you got your shoes! Squat is looking good, but I think you could still aim to slow down your descent another notch.
Bench:
You are pressing the bar straight up instead of up AND BACK. Think about pressing the bar in a perfect diagonal line from the spot on your chest back up to lockout. This will make some of those tough reps a lot easier!
Position your feet flat on the floor with your heels down and your shins close to vertical. You would probably benefit from elevating your feet on a pair of 25 pound plates because you have shorter tibias. Once you adjust your foot position, push backwards on the bench with your feet during the set to tighten and increase the height of your arch.
