Looking at your gear briefly, I would say you would be lucky to do MP4/5, your gear is more suited to MP0/1, your monk looks like mine when I first started out. A few things stand out:
1) You have no increased attack speed (IAS) items. The key for sweeping wind builds is too hit often and crit often, generating the largest number of tornadoes possible.
2) Get a cheap Echoing Fury (EF) for your main hand item. You can probably get a 1000 dps +dex with a socket for a few million gold. Most important is the + attacks per second stat - ideally you want +0.25 atk/sec, but that may be over budget for you unless you find a good deal, so get what you can. The reason that is important is because +atk/sec will apply also to your offhand weapon.
3) You have too much vitality. You can safely get around with 20k-30k hps, as long as you have enough lifesteal/loh (more on this later).
4) Looks like you went +fire resist, which I started out with also. You can find yourself some nice cheap items like Fire Walkers and Cindercoat.
5) Long term, the way to survive high level MPs is to increase your DPS high enough that it also increases your survivability through lifesteal (LS)and life on hit (LOH). By the time you get around 80k-100k dps, you should be able to almost never see your HP globe go down except to elites. Initially, you want to gear up with +LOH, because it's cheaper and more effective. Once you hit about 70k DPS, Lifesteal becomes the more valuable option. Also remember, Lifesteal works on the tornadoes you generate off of Sweeping Wind, but LOH won't.
So start shedding vitality, find some increased attack speed items, get yourself a decent EF, and work on more LOH before adding on LS. But imho, definitely focus first on getting IAS items and a nice EF.
