[Monk] Have about 15mil gold, looking for upgrades

Title says it all. I've done some searching through high end monks and what they are wearing, but could use some expert advice on what to upgrade next. I can pretty much roll through Alkaizer's A3 MP0 run (though it takes me about 30 minutes to do so). I'd like to get to the point where i can cut about half my run time as well as start to farm for keys. Here's a link to my profile : http://us.battle.net/d3/en/profile/Wolfcastle-1898/hero/350172

Thanks in advance
