I believe you've got the same model ( SE ) as me, so you need to undo the fog light surround cover ( one screw ) then prise the cover off, its a bit of a tight fit so you'll have to give it a good tug, the cover is made from a quite sturdy plastic so don't worry too much about it breaking.
Then you'll find that there are three screws holding the fog light in place plus a spring fastening clip along the top edge of the light fitting which clips the light fitting to the bumper, prise that off using a small screwdriver or something that will fit in the U part of the clip.
The bulb holder is a baynet type fitting on the back of the fog light, once released the bulb holder has to be squeezed in to remove the bulb, once off I think its fairly obvious what bit you need to squeeze in to release the bulb.
The only tools you should need will be 20 and 25 Torx bits
Remember to test the bulbs by turning on the fog lights BEFORE you reassemble the the fog lights and their surrounds.
Best of luck
