Mate; it's pretty straightforward, if you're unsure, take a few pics before you pull everything apart and above all TAKE YOUR TIME.
RDA rotors are fine; I reckon the Remsa pads sold by GSL Rallysport (forum trader) are great value with an excellent heat range, although they are a little dusty. Still, I'd rather have brakes that work than clean wheels.
GSL are great to deal with; I've ordered pads in the morning, and received them on my doorstep the next morning; from QLD to Blue Mountains NSW! Seriously quick service!
