Gloves/Chest/Legs should be your next purchases.
I would say go for Chest Next. The T10 264 gloves are comparable to the Gauntlets of the Kraken, and if you can get lucky and get them from VoA, then it's a decent sidegrade to the gloves. If you don't like relying on RNG drops then maybe pick up Kraken gloves but in your position I would go Cata Chest then Gauntlets of the Kraken.
Having said that, you need to do some farming. You should try to not use frost emblems (at least on your main, maybe you have an alt to feed you extra emblems from) to Craft Pillars of Might. You might be surprised at how fast you can make 7kg (roughly what it costs to get them made these days, maybe 8 or 9kg depending on the server) especially with Alchemy as a profession and especially if you can farm a lot of alchemy mats with an alt or just farm minerals with your mining and sell them to buy mats for Alchemy to make some major dolla dolla billz ya'll off of flasks and pots.
