As far as making the address show up on OpenStreetMap...congrats, you did it right and it's there already! If you don't see it, you might have to clear your browser cache.

As for facebook, no idea. Different maps take different amounts of time to update from the main OpenStreetMap data set... the OpenStreetMap website updates something like every minute or two, but for instance OrganicMaps only updates once a month. I would assume facebook updates pretty often because they have the money and infrastructure to do so, but I don't personally know.
