I have no real answers but thoughts that trickled in my mind as read...randomly.
Underground rivers. Definite issues for defense. Seen too many horror cave movies to trust those things!
If I was a dwarf (and I am, albeit drunk) I would have a huge grand entrance that siphons through a few defensible entrances. Each of these entrances would have GoT style collapsable tunnels that would completely seal them. They would also have some bad ass doors equal to about 100 Hodors before you got to the collapse. You have an opportunity to have many layers and murder holes. Gas you mentioned...probably just deal with those deaths and collapse it to keep from more happening.
Once you are in there will be minor defenses on scale with a castle's types. Hallways, doors, more murder holes and windows. Depends on the state of the world you are in how crazy you get with defense too. But once through the main you are in a pitched battle more or less.
Underdark I see it similar to the entrance. Major defenses along the main routes to the underdark. Try and keep them consolidated and/or funnel them into areas that you can defend. So entrance and underdark have major defensive networks with a comfy little home and mining caves branching out from the interior. Some secret escapes and such. Maybe something that doesn't quite breach the outside but with stuff in place for a quick explosion or some magic hammer or something. Keep the hobbits away from my gold type thing.
Fun ideas. Haven't thought much about it. Dwarves just live in holes, right?
As far as the
