Incredibly the shade damage does not intrude into the image, and the lens seems to work OK!
Trying to bend the lens petal back to shape may make matters worse. If it's working OK, just roll with it and be thankful it's still usable or get it replaced under insurance.
The lens coating is almost certainly damaged, so you might get the occasional problem with flare. Trying to get a lens element re-coated won't be cost effective. In forty years I've never read of anyone getting that done.
