There's also little to no wind to keep the dust floating or stir up new 
dust. It should all settle relatively quickly.

Well, since those asteroid cities could never exist, and only do so by 
magical laws of physics that also don't exist, I don't think it's a big 
stretch to just ignore the problem. Just assume that the influx of dust 
swept up from the asteroid's orbital path is equal to what the asteroid 
loses by driving it out of the air envelope and that's that.
