Is there anything I'm supposed to do with the "WAAS CH 90502 W09A"
information? Are there receivers which require you to tune the WAAS
corrections in manually? I've always assumed that a WAAS-equipped GPS
would just do that automatically.

The 480 does. I'm sure the 430-W will as well. I suspect this is
one of those things like the TACAN channel numbers put in there for
"other" users.

Those WAAS channel numbers are part of a spec for "Delta 4" receivers
typically associated with an FMS installation that doesn't have a
database of the whole procedure, but instead uses the the channel
number to indentify the Final Approach Segment (FAS). The FMS is used
to navigate the procedure up to the FAF,and the Delta 4 receiver flies
the FAS. This is similar to how an ILS is flown using an FMS.

Your 480 shows the channel, but it isn't necessary to pull up the
procedure.
