Strange.... my settings posted above are spotty now at best.
Also weird is that I've been traveling lately and without changing any GPS settings here's what I've experienced:
Raleigh, NC - spotty aGPS success (maybe 40% of the time I get a lock).
San Francisco, CA - no locks ever (even dialed *22899)
Dallas, TX - airport stop-over - no locks in the hour I was sitting at my gate
Washington DC - spotty aGPS success, but with a noticably higher rate than in Raleigh (maybe 75% locks).
