Got rear ended - does this bumper look right? (includes PICS)

[clubba]

Am I being delusional? Wife got rear ended and we took the X5 into Kuni Collision Center in Beaverton, OR. First they screwed up some electrical wiring which caused the key fob to not work - took it in to get it fixed. Now the lift gate creaks like an SOB. I found the two clip-like plastic pieces in the rear lift gate channel just resting loose on the bump stops (I do not think these are related to the squeaking, but I don't have any clue what they are). The bumper appears to gap more toward the rear and it looks like i can see clips in the gap. Also, they left some yellow tape under the rear spoiler on both the driver and passenger sides (driver pictured). Am I just being paranoid, or does this look off to you too?
