^ I'd definitely argue for getting the fork replaced as part of the damages. However, there's no need to replace the frame out of fear of latent damage. The frame is steel, and its not going to fail catastrophically from damage you can't observe.

The LBS can look the frame over, if its not twisted out of alignment, and there's no dents, buckling in the tubes, or cracking in the paint, the frame is likely as good as ever. If the frame took a hit that wasn't sufficient to cause any of the above, and it rebounded to its original shape, it didn't cause it long term damage, which is a good thing about steel. You can bend it over and over, and as long as you don't bend it too far it doesn't hurt it.
