Personally, I'd do the pads and discs myself, now having done a whole brake conversion. You don't actually need to take the calipers off the car, just undo the carrier slider pins enough to get the pad out. The discs can then be taken off.
As said, get all the tools, watch as many videos and read as many guides and take your time. No mechanic was born knowing how to do anything, they all had to learn at some point.
