With that said, I do have to make my reservation (or update it after it's booked) with my AAdvantage number, or else AA won't know of my status for this flight if I use my BA Executive Club number, right? Sorry if these sound like basic questions, but I'm still new to award travel.

Yes you can have two frequent flier numbers associated with your booking. Once you have created the booking on ba.com, you can have your AA number associated with it.
You may either do this with one of the website tricks we have listed here or you can call AA to get it sorted.
