Sorry to hear of your troubles, i wish your wife well for a speedy recovery. I suffer back trouble myself, no metal rods as yet but i can definitely relate to, if not fully understand the discomfort your wife is in.
Looking at your pics, the B post and C post are both bent, the chassis is bent (hence the misdirected NSR wheel) so would almost certainly need to be jigged and jigs don't come cheap, even on a rental basis to bodyshops. Then there's the obvious costs of the doors, any other panels (eg wheelarch) and so on plus the cost of a complete respray so that the paint matches. Wouldn't be much different for a partial respray as almost a complete side will need painting then blended in to the rest of the car, resprays are generally quoted at between £3-6k at the moment, depending on the quality.
I hope your insurers start playing the game properly and give you a decent settlement offer.
