I think my rotors are OK; the front rotors actually were replaced about
15,000 miles ago, but they still look kinda thin.  I probably won't
replace them now, but I think they will need replacement soon.  The back
ones still look OK, though.  Anyone know how thick they should be?  I
can check them out when I take the wheels off.

That's what I'm afraid of!

I'm pretty sure it's pads--aside from the squealing, which started when
the pads had about 20,000 on them, has gotten much worse, and it takes
considerably more pedal effort to stop the car.  Also there's a little
grinding noise now, too.

In fact I don't mind the Audi pads that much except for the dust, but I
can live with dust.  I just wanted to get cheaper pads.
I do want to do this tomorrow because I really am worried about the
amount of effort it's taking to stop the car; it's suprising sometimes. 
Especially after long highway trips where I don't use them much--after
driving for 95 miles yesterday without using them and then trying to
stop on the exit ramp of the freeway, I was never able to stop the car,
though it slowed down much more after I put both feet on the pedal.  (I
checked the brake fluid, it's fine.)

That's my plan.
