Head over and get all your timeless isle loot, that will at least give you better than boosted gear. New UBRS will have i550 loot coming from Tuesday on, which will be more than you need for early WoD.
As far as money goes, my realms AH has pretty much come to a screaming halt. Hardly anything is selling as a) people are saving up for WoD and b) mats price will sink as leveling professions will become WAY easier in WoD. This happens every time before a xpac hits, so no surprise.
You can make easy money by just doing dailies and if you have enough time, cap out your JP/VP for when they convert it to gold on 14th.
