Good job, you should try with the whole bevel polished, not just the microbevel. For push cutting such as in shaving it makes big difference (well, depends on your definition on big).

How do you know when to switch hones - the short answer is experience. You want to move at the moment just before the edge breaks down and develops burr or microchips. Before or after that and in the best case you have to spend more time with the next hone, in the worst case you have to redo it. Different people use different tests - how it feels on a thumbpad, how it interacts with various kinds of hair, how it interacts with the hone, some just count N strokes and move on. The common thing to all those methods is that you have to calibrate them and make sure they give you consistent results i.e. back to my short answer.
