the call to arms weekend is the same for all Battle Groups right ?

So eye of storm weekend for this week. That's your answer. Queue for tol barad every chance you get. Don't forget wintergrasp weekly.

that's about it.

I actually counted. I do random BG non-stop (queuing tol barad every chance I get). Including the queue time, I get about 2k honor per 5-6 hrs. This is killing my health lol. Horde wins 30-40% BGs in bloodlust.
