Weird Braking
I just had all my brake pads replaced and flushed the brake fluid on my 2004 UL with 151k miles. Before this job it exhibited a creeping behavior at stop lights where I would have to really push the brake pedal down in order to make sure the car was stopped. After I had this most recent brake job nothing has changed. The idle is normal in neutral, under 1k rpm. I almost hit a car in front of me today at a stop light when I leaned over to the passenger seat to grab my iPad and the car started creeping forward! Scared the crap out of me!
Also, when I release the brake pedal it makes a funny squeaking noise that I just noticed about a month or so ago...and only because my music was off. Any ideas what these issues could be???

I'd have the brake master cylinder/booster and all brake lines/hoses thoroughly checked.

The "funny squeaking noise" and "creeping forward" are not likely to be related.
For the noise: Did you install new rotors or have the existing ones resurfaced? Did you use a shim between the new brake pads and the caliper piston?
For the creeping forward: Based on your comment about pushing hard on the pedal to stop the car, suggest to check for leak at the vacuum line, the vacuum check valve, and the grommet to the brake booster.

During the winter I noticed my brake pedal squeaking when I would release the brakes as well. It was very noticeable in stop and go traffic. I'm not hearing it now that the temps have increased.

No disrespect to your local mechanic, but you may want to search for a shop that specializes in performance cars and mods (especially ones that do BBK upgrades) and have them assess your situation.
No argument avoiding the dealerships; if not a performance shop then an independent that offers Lexus/Toyota services since word of mouth, good reviews, and reasonable prices drive their business. Yelp can be a good starting point.
