The front bumper is held on by 4 like 20mm bolts and there are 2 bolts/brackets that are hidden near the corner of the bumper that will likley break when you try to remove but you can get them from toyota for like $5. that all that is holding your bumper to the front of your truck 6 bolts.
The bumper and valance come off as one unit then you can remove the valance easy.
Don't forget to take the park light/turn signal bulbs out before you remove the bumper they just twist out.
I have taken my bumper off allot so if you need help let me know.
I can take pic's too if you need.
The grill is held on by a bunch of little clips that you push down on with a flat head screw driver and pull out on.
