You got lots of great advice already.
I have an oversized wooden cutting board that I use for kneading bread dough and rolling pie crust. My house is on the cools side and I never have any problem with dough rising. If the room is too cold, it will take longer for the dough to rise, but it will eventually rise, even in a fridge.
I too, make cinnamon buns the night before and leave in the fridge overnight.
I also keep yeast in the fridge or freezer, it does not harm the yeast for it to be kept cold. I use a brick of yeast every 6 months or so.
