Welcome to the zone! Very similar looking E30 to the one I ran for over a dozen years, until it met its end about twenty miles from where it was born, at the hands of a flying porker, although mine was a 325i, and I can see yours is a four pot.
The rear valance is available as part of the complete rear panel, but your dent is on part of the rear right side panel, and I think that looks repairable as it is, with the aid of a carefully wielded hydraulic body jack. This area of the car has a textured paint finish, so the work doesn't have to be absolutely perfect.
The front panel is very thin in that area, and again, that should be repairable. You should be able to just about sort that by hand.
Before getting stuck in though, do a serious rust hunt. There will be some, although one common area, around the rear tow hook, looks good in your pic.
