Tom - The accident I had with my current VX was also on the driver's front corner and required a new hood, fender, front cladding, headlight, and a bunch of other miscellaneous stuff. In other words, it sounds like you had a very similar accident.
If you're interested I can send you the itemized receipt from the body shop that fixed the damage so you can compare it to what USAA received from your/their body shop. That should allow you to do a true apples-to-apples comparison for the insurance company that may be more realistic.
FWIW the damage rang up at only $4,672.90. Unless your VX has frame damage or some other issue that's not readily apparent from the pictures I think you're getting hosed.
