Choice of Brake Pads for 2001 530i

The brake wear light just came on in my 2001 530i. I am not sure whether it is alerting me to wear on the fronts or rears but, at 68K miles, I plan to replace all of them. What I am looking for is advice on the pads to buy. I am mostly concerned with the annoying brake dust. I don't need exceptional braking power or especially long life. Any suggestions? Also, how about the need to replace the break wear sensor as part of the job? I appreciate any inputs. John Ann Arbor MI
