Skoda Superb 1.9 accident

I was rear ended as I sat in a queue last week. I was shunted in to the car in front. cant see much damage at the back - bumper has strees fractures and is a few mil out. The front bumper id split and deformed. I notice a dent in the inside of the grille and a sharp crease (pushed in 4 inches) in the metal beam at the front. I have arranged to have it looked at by a VAG body shop on Wednesday. What else do I need to check on to make sure it is sorted out properly? (the garage I purchased it from told me to use an authorised repair shop as the ones earmarked by the insurance copmany were usualy no good)
