Defend SH and IW for alliance. IB tower and TP for horde. If those 2 bunkers/towers stay up the enemy won't get the boss down and you get some nice bonus honor if they're still yours at the end of the battle(they cant be assaulted). If the bunkers/towers in DB/FW get capped it depends on how many horde/alliance are in there. A couple of good players can really be annoying in those bunkers if you want to recap it, so make sure there aren't to many enemies and you got some friends with you.

Concerted Efforts -> 930 honor. I had a lot of marks from the old battlegrounds, so a won Strand of the ancients would give me 3x 930 + 1k from the BG itself. But this depends on the marks you have. You don't need them to buy the pvp items anymore.
