Regarding 1:
If you want something unique, I was always fascinated by the prospect of the dwarves having truly functional tech for their mining and building. They could have created "golem-like-machinery" for excavation and edifice construction. Perhaps their Runepriests found a way to bind Earth Elementals to front-end loaders or boaring machinery or other harvesting devices (perhaps "golem suits" like the mechanical one that Ripley used in Alien/s). You could have a few kobold clans who have mastered this "golem tech" and use them as sentinels or pilot them themselves during combat encounters.
