Welcome to the forum.
That list fits with what’s currently regarded as the meta for Chaos Dwarfs. There are certain variations but the main stuff is already there (the two characters in this exact loadout, the iron daemon, min Infernal Guard, Hobgoblins) This will work great!
The dark days without model availability are thankfully behind us and you can find lots of excellent models both in the 90s Big Hat style as well as Legion of Azgorh Style (e.g. Lost Kingdom Miniatures). The Warboss on Maw Crusha is obviously a great choice, it’s just a little big for the base and needs some working around.
