brake wear indicator has come on - can I do this?

05 clk320 cabriolet 40K miles

So, the indicator warning just came on. I have done many brake jobs in my time on american cars. Never did one on a benz. Anything special about it? Do I need some weird special tool?

Also, there seem to be a bunch of manufacturers of pads. These have lasted 40K miles. However they give off a lot of dust. Any recommendations for a good set that is low dust, and good performance. Not looking for anything ultra HP. This car is my wife's fun car. She drives it pretty conventionally.

Thanks.
