1. Loosen L or R Wheel Nuts a turn or so.
2. Jack front (L or R) on Subframe and put an Axle Stand under there as well.
3. Remove Wheel.
4. Undo the two Caliper mounting Bolts (19mm Hex), pull the Caliper off the Disc and hang it out of the way with a piece of Wire/String.
You may need to push the Pads back a little if your Disc is worn a bit, as it will have a lip on the outer edge, just use a large flat-blade Screwdriver to lever them away from the Disc.
You don't need to worry about damaging either the Disc or the Pads of course, as you're replacing both.
Make a note of how all the parts (Springs, Stainless Rub-Plates, rubber Boots etc) fit on the Calipers, I find taking a few Digital pictures helps the first couple of times you do something like this.
5. Unscrew and remove the two pointed locating dowels (12 or 13mm Hex I think), they also secure the Disc to the Hub.
6. Pull the Disc off the Hub, it may be reluctant to move, tap it with a Hammer/Mallet if it is.
7. Clean the Hub, Caliper (and all it's parts) thoroughly, reassemble, and fit the shiny new Disc and Pads.
I'd also flush through some fresh Brake Fluid when you bleed the Calipers.
I think that covers it.
If I've made any glaring mistakes/omissions (I've been awake for 27 hours straight!), I'm sure someone will point them out.
I'll try and find some pics too.
