I've been chasing the break-screech for several months - same feedback. In late December I was told either new pads or spacers would be availalbe in January to correct the issue. NYC taxicab is a interesting description - I used School Bus and Dump Truck a few times.
I also have a squeak on the WIndshield / dash area that occurs in cold weather. Minor bumps in the road and turns into a parking lot that make the car flex create the noise. Inside Rearview mirror also vibrates (a lot) when the sun roof is open. Makes me wonder about the body handles flex.

I own a 2007 GS 350 AWD - best car I've ever owned - I had the same problems a year ago and took it to a Wilkie Lexus, Haverford PA - the problems were repaired in a few hours - to stop the windshield squeak, techs need to remove the dash - I was told the brakes and windshield are a known problem and items available for repairs - call the Lexus Customer Service toll free number for advice - it's in your manual -

The TSB for creaking windshield I posted previously did not fix
the creaking noise. I inserted a soft foam as a cushion between
the windshield & dashboard on both driver side & passenger side. The creaking noise is very much gone every time the
car runs over a bump now. The insertion is between the vent
hole & a small speaker on the dashboard, on each side.
The TSB for rearview mirror fixed the vibration. The dealer
has to replace a mirror. The mirror costs a fortune, but it's
covered under warranty.
Still waiting for a fix to the brake squealing noise. Dealer will let
me know when the new parts arrive (ETA in late Jan 09).
Today outside temperature is below 32F, and the brakes squeal
every time I used them. Kinda annoying.

Dealer let me know the new front pads and rotors are available to
fix the brake squealing noise today.
Did anyone have yours replaced?
Have an appt to replace mine in 2 weeks.

I just took my car in today to have them replaced. Seems to have worked but I only drove it for about 30 minutes (drive home from the dealer) so my hope that is the quiet continues!! YEAH!!

I hope the new pads will also fix the excessive dust issue.

I own a 2007 GS350, and have the dash rattle and brake screech problems. My dealer told me the dash is a 6 hour fix, and I have to make an appointment far in advance. As for the brakes, I have had a repair by the dealer (didn't work), and when I returned, the repair writer told me that there is nothing that can be done as no parts are available. I have called Lexus twice (latest time 1/14/08), and was told "the engineers in Japan are working on a solution" When I asked gor a time fram (eg a week?, month?, year?) I was told that they couldn't say. This is pure bull____ because they are still selling $50M cars with both of these defects, and when they do ever get a fix on the brake problem, there will be a serious time backlog.
I finally took the dealer to task, and told them I deserved a complete brake job right now under warranty, and if the problem arises again before a permanent fix, I should continue to get brake jobs under warranty. Who knows if they will ever fix this problem. By the way, the dealer agreed.
I think if all GS owners took this position, I would prove so costly to Lexus they might get off thier duff and solve the problem

I have had the brake pads replaced(I believe they are ceramic, but not sure), and it did fix the "screech" problem. An added advantage is that the dust issue is now almost non-existent. This was done two months ago, so it appears that the fix is lasting.

I had the dealer fix the ticking(or creaking) noise on the windshield, and it worked for a while. However, I noticed a little bit of ticking recently when it got really cold. Could you clarify where you placed the foam? Is it between the defroster vents and the windshield? Or is it on both sides in front of the speakers(there is no vent in that area). Or, are you saying the insertion point is midway between the defroster vents and the speakers(I think that is what you mean, but wanted to make sure)? Is it visible either from inside or outside the vehicle? Thanks.

Your thought is correct.
The insertion point is midway between the defroster vent &
the speaker on each side.
I used 6" (wide) x 1 1/4 (deep) x 1/4 (thickness) vibration
damper pads, one on each side.
With a little force, push the pad down the
gap between the windshield & dashboard until it's not visible
from the inside. No, it's not visible from the outside (that was the
first thing I checked after I pushed it in).
Foam may not work because it could still cause noise when the
dashboard pushes against it when the car runs over bumps.
