There are many ways to smokes a bottom round roast. Depending on the device used to cook it depends on the time it will take, for most it is a half a day process as they are cooked on low constant heat.
Cook it all day; crock pots don't really overcook anything.
Yes
It should be cooked on or before the third day. Count the day it was bought as day one, the next day as day two, and the day after that as day three.

You can cook the roast and then freeze it with minimal loss of taste if you wrap it in an air tight package. I wrap mine first in plastic wrap, and put it in a baggie (be sure to squeeze out all the air). Then wrap it again in foil.
Yes just be sure you fully cook it afterward.
Yes you can cook beef the night before and reheat it the next day. Keep the heat low and reheat the beef in liquid to help prevent it from drying out. You should keep the beef moist.
