I think both Tim and I (at least I) were trying to say was leave the thread the way it was. If people in the future ever do a search on how to remove the starter, then the answers will make more sense.
As to your new question on bearing. I'm sure there are going to be different opinions on this. But my own understanding on this is that bearing manufactures pack a thick grease inside for longevity reasons, and although it has more resistance and attracts dirt, the grease really isn't going anywhere. However, when maximal performance is called for (meaning you would want lower rolling resistance), or when the bearing is cleaned with cleaners, the grease gets washed out. This is good for a while, but then you will need to relube the bearings subsequently and frequently to avoid insides getting dried out. There is really no way to repack a ball bearing.
So as far as I know, you're better off wiping the dirt and grime away from the outside and leave the inners alone. I'm interested in what other people think on this as well.
