Run the Thrall quest line as soon as possible if you haven't already done so. At the end you'll be rewarded with an ilevel 365 cloak that is a direct upgrade to the Hyjal reputation ilevel 359 one.
Some odd 4k Justice Points ought to make the previous 359 VP gear available to you. Even if you have already gathered up most of what you want you could still pick up the boots, the retribution legs and the tanking cloak to make your threat set a little better while still maintaining decent tanking stats.
Oh, do pad out your PvP set immediately if you already have a partial Vicious set. You want the spare room for gaining more honour to make sure you fill the set when you start grinding Conquest Points next week.
Apart from that it's time for the slow and boring grinding of dailies to unlock the 365 gear that is sure to be a benefit to us casuals. While it's mostly superfluos for hacking away in five-mans it's certain to come in handy when we start making serious attempts at the first Firelands bosses.
