A report from a local newspaper said that there were a very few small leaks in the museum's roof, and that none of the exhibits inside were damaged.
The museum aircraft outside the building had a rougher time, getting moved around and hitting other aircraft, and there was some damage.
I have yet to see any photographs showing significant damage, and have seen some photos where the buildings looked fine, so at least some parts of the base survived.
Bush flew in there this morning, so we can assume the runways are intact.
