So my battery is fried, it won't hold a charge and I've had to drive around with a jump pack until I can get to the dealership next Monday. However, I just found that I can get a Bosch battery from Pep boys for half what the dealership is charging, so I figure I can just swap it out myself this weekend. Now, the key question is, if I do that, can I use Vag Com to program the battery once I swap it, or do I still need to go to the dealership?

you can swap the battery yourself, as long as the new battery has the same specs as the original one. To code it you will have to use the vag-com and enter the serial number of the battery. Entering the serial number in the coding information will tell to he battery manager controller that a new battery has been installed.

Does it matter on the brand of the battery? I've heard that some of the after market alternatives are a much better than factory. Do you know what other brands (Rayovac/Bosch OEM) we can use?

Audi uses Varta and Bosch here in Europe, i am not sure about the approved battery types in US, but according to Audi Specifications the battery must be 110Ah/520A, normally any battery with this specs or higher will be OK as long as it fits in the battery box underneath the driver's seat.

Any Bosch with same or higher specs. Check also the size to fit in the battery box.

Honestly, I don't think it matters. You can just leave it the way it is. I have a 2005 A6 (that is now my spare car, I replaced it with a 2015 A6 Prestige) and the first time I replaced the battery with a VW/Audi Genuine Battery it wanted the model and serial number off the sticker. But the second time the battery didn't even have a serial number on the sticker so I didn't change the coding. The car was just fine.
