C0da, is yours a 2006 GX? I just took a look at the front of my car ... and it is different from mine (an LX). I don't have those cut-outs for fog lights (yay!) and my grill is a slightly different shape.
I was also looking at maybe making pieces to put where you have your red squares ... but I can't get behind that area. I was thinking of using long, thin bolts to keep black plastic pieces in place ... but not if I can't get my hand behind the bumper cover.
