Doing brakes for the first time

I am doing the brakes on my wifes 2004 325 wagon for the first time. 4 rotors, pads, and sensors. Is this straight forward or is there anything special I should know? The car has the sport package. Does it have the same rotors as non Sport package?(they wear really fast)
Thanks in advance, Rich

nothing really special... just as long as you know how to do breaks. take em off, clean up the calipers etc. put it all back together and done. loli was doing breaks on BMW's when i was just entering high school
