Sorry to hear about the crash... never fun I know.
Getting hold of replacement panels isn't difficult but getting the right colour may be a problem. If you can get hold of the right colour (you have Star Blue panels I seem to recall), it would be the simplest and cheapest way to deal with this (assuming that the car is OK under the panels with regards to the crash bar et al).
If you need to repair + paint them, I am reasonably confident that they can be repaired like fairings can but if it is beyond a few cracks (sections missing and major cracks), I would replace the panel and then get that painted if needed to.
