For the pads, all you need to do is loosen wheels nuts a little, jack up car, remove wheel nuts, remove wheel, on the brake caliper, remove to retaining clips and pins, slide pads out, push piston back in with large flatblade screwdriver, slide in new pads and reverse assemble from clips and pins bit.
Don't forgot to take the cap off the brake fluid cylinder so pushing the piston back is easier.
You could also while everything is off and the new pads are in, bleed the brakelines or replace the brake fluid with new.
Really not a big job and once you have done it, you'll wonder what the fuss is all about
This is what you'll be looking at basically (clips and pins are out at this point)
