OK. Here's how ya do it. Get a big ass beach towel. Lay it down on the front in front of your car. Pop the hood. Remove the wheelwell screws. Remove the screws under the hood.
Go on one side of the car. Doesn't matter which. Grab the bumper cover right by the wheel well and pull it straight out. It should pop out a little bit. If you have a little difficulty, push up on it slightly -- as you'll need to get the hidden slots of the bumper up and off the plastic tabs on the bottom part of the fender. For reference, we're talking about the area that extends along the top of the bumper straight out toward the headlight.
Once the side of the bumper is flopping around, you need to lift it up, away and toward the wheel. Sounds weird, but there's a plastic hook that sits in the vertical seam right below the parking light. To unhook the bumper -- you need to get that vertical bumper piece moved back -- then out.
Once you've done that -- repeat on the other side. The bumper should just flop forward onto your towel. The styrofoam cushion will, too.
From this point, getting the grilles in is pretty simple. Just pull those little bastard razor blade things off and replace. To get the bumper back on, just position into place and gently push. It more or less will pop back on. Just be sure you tuck the plastic wheelwell liners behind it before completing the mounting.
If you break any of the eyelits on the bumper -- just Krazy Glue back into place and wrap with a thick aluminum tape. It will hold. And be sure your new grille is solidly into position before putting the bumper back on, too.
Seriously? This project isn't THAT hard -- it's just that the bumper slots, bumper hooks -- and those stupid razor blade things just aren't clear cut. You have to finesse every f'n thing.
