I just left the airport, so I can't help you with the bleed screw's tube size.

I can tell you that I bled my brakes both ways.. top-down and bottom-up (as the link describes). I wish I had tried the bottom-up approach from the beginning.. it was a lot easier, and I had fewer stubborn air bubbles. Though even with a couple bubbles, they didn't feel spongy.. I just didn't like seeing them in the lines.
