That's a tough fix as it's right on the corner crease. And if you actually look closely down that quarter, you'll see that metal push inwards away from the corner, and then you'll have a spot that bulges out a bit (the pushed in metal has to travel somewhere). You can try and massage that metal out with a hammer and dolly, and then use some filler to recreate the corner line. You obviously want to use as litter filler as possible. As far as your bumper is concerned, a good chrome shop will work out the dent if you went the rechroming route on the bumper (not sure if you think it's worth it or not.)
