Eye for an Eye has a great set of tips up for the Strand of the Ancients battleground. Their tips are aimed towards Ret Pallies, but they're useful for almost anyone, and especially any melee-based classes. And the general idea -- focus on the relic and getting to it, not the players attacking you or other teammates -- is great for anyone to know.
I don't know what it is about Strand and Wintergrasp that has pulled new players into PvP, but there's something new there -- DanO also has found himself PvPing in those places when he never guessed he would. It seems like the objective is a big part of it; the goals in Strand and Wintergrasp just seem more epic than the skirmishes in Warsong and Arathi Basin (and they come with none of the major issues in Alterac Valley).
Still, while most of the tips are common sense, some of them are worth listening to if you haven't though of them yet (I liked the tip about sniffing out Rogues around the tanks -- whenever I've played Strand, I've always headed for the walls, but protecting the tanks is a great tactic, too). If you haven't tried either of the new PvP areas yet, give them a look, and bring these tips along with you.
