the majority of brake noises come from replacing pads with glazed rotors similar to what tech said, i always suggest replacing rotors when doing pads if the rotors show any sign of a large lip around the edge, any scoring, or any heat spots.
The stock pads are quite good. If you want something a little more aggressive, I'd recommend the Porterfield R4S. They don't squeak, and only dust a little more than stock. I run them on my 95TT. My local Toyota dealer stocks them for the MKIVTT. PM me if you need his contact information.
