If you download the AA app and attach your reservation then you should be able to check-in on the app, although since you have bags you'll have to check-in at the airport anyways so it doesn't really matter. With your BA status you can check-in using the priority/first class check-in desks at SFO and use the Admirals Club at SFO as mentioned above. Your oneworld status gets you a hold baggage allowance so there's really no reason to worry with calling AA or anything like that.
