DO NOT TAKE IT TO THE "PREFERRED SHOP".
Think about it. Their "preferred shop" will work to the insurance company's favor, not your's. They will price out used parts, and only replace the bare necessities.
Take it to a shop you are comfortable with, and make sure they are using OEM replacement parts, and are returning the damaged area to like new condition.
As far as the deductible: Mention you have a 500 deductible, and just ask "if they can do anything about it". Hopefully they'll be able to help you out. Maybe you can source your own parts to save some money, and offset the deductible. Not likely anything will work though. If you can't afford the deductible, you should be paying more for a lower one. I have a 100 deductible on my LS. That's a lot easier to come up with when/if I have a claim.
