mauiUAflyer is right. You're a 1K, and with the SWU you are "officially in the cue." Nothing much more you can really, except wait for it to clear.

In my experience with Asia routes, the airplanes can be quite full, so very hard to try and predict/game the system. United seems to do a good job keeping track of your request in the system.

I believe the only two things in your way for the upgrade is someone purchasing a tickect in F or C (whichever cabin you are upgrading to), or a USG submitting a SWU for the PA waitlist. You may not know about your upgrade until you are at the gate (this has happened to me several times in 2008).
