While not dust-free, please try the "yellow-box" Textar pads, which is the "European" MB OEM composition.
IMHO, less dust than the USA or Textar Pagid's, great stopping power cold, and good fade resistance especially under HEAVY repeated use (I use them on the big-track of Willow Springs, going 125 MPH down the front straight, no fade), and fairly easy on the rotors.
The Textar's come with circumferential (sp?) dampening pads. I also re-fit the stainless-steel shims that originally came with the pads and use either MB brake grease or Permatex synthetic/green brake grease between the shim and pad, and the shim and pistons, and I've never had brake squeal.
