Is 1000 grit good enough?

As far as I can tell from the posts, this is how I should lap: You are supposed to draw a 1 inch by 1 inch grid in pencil on the hone and then use either figure-8 or circular motions until the grid is completely gone. Both sandpaper and hone should be wet. IS THIS CORRECT? ANY ADVICE WOULD BE GREAT!

If sandpaper is used and any grit is embedded in the hone, I understand I need to use a brillo pad and running water to buff the surface, but will I be able to actually see the grit, or only feel it?
I suppose it would depend on how far out your stone is. Mine seemed far from flat, so the lapping stone did most of the work and then the sandpaper did the final finishing. It would have taken forever and many sheets of sandpaper.
