From my experience on Peugeots, however it cannot be very different.
1 Loosen wheel nuts.
2. Jack car up and then remove the wheels.
3. Wrap old cloth around the brake fluid reservior, and remove the cap.
4. Remove the brake pads, and push the piston in the caliper fully home. This is when you may get spillage of the fluid out the brake fluid reservior.
5. Undo the brake caliper bolts to the hub, and support the caliper.
6. Undo the brake disc screws, I have found that using an impact driver on these to be very helpful. It may also be a good idea to get new brake disc screws as the heads are prone to rounding.
7. Remove the disc, it may need a tap with a hammer, but usually they will almost fall off, then clean the hub to disc mating face.
8. Place new disc on (perhaps with a smear of copper grease) and do up the disc screws. Now I normally just do these up hand tight and have never had a problem.
9. Re-fitting is the reverse of removal, however I would again use copper grease on al the nuts and bolts, as this helps if you later then need to take it all apart again at a later date. As for torque setting I usually make sure everything is done up really tight by hand, however this is up to you and you may wish to use the manufactures torque setting. It is unlikely that you will have got air in the brake fluid so unlikely that they will need to be bled, however take it easy to start with to allow the breaks to bed in.
N.B. You should always put in new pads (with a smear of copper grease on the back of the pads. DO NOT GET THE GREASE ON THE PAD TO DISC AREA) with new discs, however that is up to you.
