Others may know better, but I thought it was very important to drill a small hole into the bottom of the bracket and I wound a grease nipple into it. It took three minutes and now I can keep grease on the bearings. It's easy if it's apart.
While filling the BB with grease is not necessarily a bad idea - think about it. If your spindle was turning in the bearings 24/7, would not the cranks 'n pedals be turning also?
