I'm having trouble interpreting the information because of the layout, but that may just be me. The camber is typical. Beyond tire wear, all that really matters in terms of how the car tracks down the road is the total thrust angle.
Bent trailing arms aren't uncommon on cars that have had rear end damage. They're a lot of work to replace, though. I've done a few E30/E34 ones and it takes me a good half of a day or more...that's not even messing with the bushings.
