i've replaced them on an older fiesta 95 i think and all is pretty standard apart from ford calipers being held in with hex or star bolts, so a standard socket set will not remove the caliper bolts. it maybe different on your model, but worth checking first. you can pick up a set of these relatively cheaply.
also make sure you have a threaded clamp, much easier to push the pistons back with, although you can use a piece of wood and push it back yourself.
don't forget to take the top of the fluid reservior too before you try to move the pistons, thats about it, make sure you allow the pads to bed in, i.e use them gingerly for the first 200 miles and use the gears more to slow down, try to avoid harsh braking, this will vastly improve the life of the pads.
one other thing, applying a bit of copper grease to the back of the pads, should stop any squeal, and make sure you replace and pins / shims with new ones.
