Alright, so I finally got my front upper grill in, so I snapped some pictures. The triangles that are being referring two are in the first four pictures. I did not capture a few steps (three clips in the fender wells + a screw. 6 pop up clips under the bumper that attach it to the skid pan.)
Right hand side triangle, this pulls straight up, and is held in by a single body clip and two plastic ears that mate with the bumper

Top bumper cover. This stays attached to the bumper. Removed the 5 yellow circled clips. They are pop up clips and not Christmas trees.

Single bolt under the right and left fender lips that were covered by the triangle trim pieces, 10mm. Would be best to use a swivel if you have it for these.

Front view of car, bumper removed. Yellow boxed items are places the bumper clips into by pressure. Blue boxes indicate notches on the front plastic frame that the bumper sits onto. Red box is the harness connection (DO NOT remove bumper quickly once you get it off the car, this harness is short)
