I find that your a) suggestion is the usual answer, which should be satisfactory because the nut holds it tightly in place. Have you campared the fit of the previous bearing with the new one? The other question I ask myself is why you have chosen a sealed bearing? I believe in the original type of bearing with a 'new type' lip seal in place of the original felt. I don't like the idea of easing the inner wall of the bearing with emery paper because there is the danger of emery dust finding its way onto the seal and causing damage in the long run.
