They said they can communicate with the ABS sensor and TPM for the alignment, just not the camera. Do I really need to go to the dealership for the alignment, or can I just have a local shop do it and ignore those lines on the camera that I don't really use anyways? Does anyone have the specs for the alignment? I know the "within spec" the dealership offers leaves far too much margin of error, and I don't want to fix one problem and create another. I am not terribly concerned with handling as most of the roads I drive are all straight shots with very few if any curves so having a negative rear camber doesn't matter much to me. Just looking for some help before I get raped by the dealership. Thanks in advance!

No, wrong.
it is most likely TOE that is causign the camber to kill your inner edges.
This is a common misconception, 'inner edge wearing' must be camber- these cars are designed for some camber, but it is how much toe that combines to eat rubber.
(I've never heard of a shop not being able to align a suspension due to 'electroncis communications issues'... very strange, maybe I'll learn something new)
BMW allows way too much toe in their spec. As I recall it can be 0.00 to 0.08 per wheel, with a cross toe of 0.00 to 0.16.
I usually set rears at 0.01, 0.02. NO MORE. If you go to a shop or dealer, and they run the machine and get 0.07 and 0.08 and cross toe of 0.15, they say "yeah, you're fine".
I have an M5 and a 996TT and both have heavy camber- but light toe, especially the rear. It works.
