You should make the dwarfs build a city kinda thing, kinda like how if you give clay soldiers, from the Clay Soldiers mod, wood they would build things. You could make a different version of that, like cobblestone and different buildings, and also make it so they are more like little guys you can watch and mess around with, not focusing on making them soldiers like the clay soldiers.
When you tame him, you should be able to name him by placing down a sign that says his name and if he's under it for 3 seconds his name becomes what you wrote on the sign. Also when you tame him (with gold ingots of course) you could dye his suit from red to another color.
