I'm not much better than you, but none of the good golfers seem to be answering, so I'll share my thoughts:
First, the "whippy" appearance of your shaft is an artifact of using a camera without a fast enough "frames per second" to catch a fast golf swing. If you are using a camera phone or a cheaper point and shoot, it's unavoidable. Don't worry about it...
Second, it appears that you're left knee collapses far too much during your backswing. You then straighten the knee out during the downswing, and that seems to keep you from keeping your hands in front at impact.
No idea if that's really holding you back, or how to fix it; sorry!
Again, I'm just starting to look at my own swing, so hopefully someone who actually knows what they are talking about will chime in...
Good luck!
