Remove grill, remove batteries(not necessary, but makes it a lot easier), remove two nuts holding the turn signal/corner lights(in front of batteries, they are hidden, but are there), take off header panel(headlights will come off with it, there are a bunch of bolts that hold it on too), take off the 4 clips that hold the headlights on. Install is opposite.
The nuts that hold the turn/corner lights are hidden pretty good, there are studs in the light housing and come through the header panel, they may or may not come out with the nut. You will need a 10mm(I belive) deep socket and extension on a 1/4" rachet to reach them. The bezels are held on with screws on the turn/corner lights. You really only need a 10mm socket, some extensions, 1/4" ratchet, screwdriver(both phillips and stright), and I use snap ring pliers for the clips on the headlights and a stright screwdriver, they can be kind of a pain. You will also need like a 4.5mm or 5mm, something like that to adjust them, can't remember for sure. I'm sure i'm missing some steps, but that is about it. Pretty simple job all around, a little time consuming though, should only take a couple hours if you take your time and have all the tools around.
