Yes, you are to drill the cotter pin hole. It's always been this way.
Do not tighten the nut "really tight". Tighten until there is no slop.
Best done with the wheel off the ground so you can make sure that the bearing is properly seated.
And yes, drill one side, pin the nut and drill the other side.
