Glad to hear you are OK.
When I had mine in for the fender, they did the estimate and ordered the parts and I was called when they came in to make the appointment to have the work done. My VX was still driveable of course. It took about 2 weeks to get all the parts in and about a week for them to fix it all up. I would definately let the shop order the parts. It may only look like cladding damage, but there very well may be damage underneath the cladding. And I used the insuracne companies prefered shop too. Like you say, you can keep taking it back if there are problems and insurance company will back you. Hopefully.
