Semtex's thread has some good install pics, but not specifically of the bolt locations for removing the bumper. It's pretty obvious really, and the service manual (it's on these forums, free PDF download) probably shows all the bolts too.
Basically, there's the 6 bolts along the front edge of the plastic cover under the engine bay (there are 10 others on the other edges if you wanted to remove the whole thing, like for an oil change), then one more bolt on each side slightly further out from those front 6, just behind the corner of the spoiler. Then you need to remove the innermost of the 3 bolts on each of the little mini-spoilers in front of the front tires. Remove all the plastic clip-thingies along the top between the radiator and the bumper (two rows of them, which should allow you to remove the strip of plastic that sits between the radiator and bumper). Finally, remove one plastic clip-thingy from each front wheel well liner (the one close to the front outer edge), pry that open away from the bumper, and then hold it open near the top to reach one more bolt underneath there that goes upwards into the upper corner of the bumper. After that, you can basically pull on the bumper near the headlights and unsnap it and it will come free.
