The first thing you need to understand - stop using paper dps as a measuring stick for where you are or where you're going.
Here is a true representation of your damage:
tDPS - 585134
tDPS vs. Elites - 585134
The next thing you need to work on in order to get to your goal is to try to strike a better balance. Your vit is quite low. You're going to need to decrease your strength in some places, and possibly your resist a little in order to get to the next level.
Vile Wards: The vit is too low. Switch these to high str, high vit, high res rare. You can easily get a 180+ strength, 170+ vit, 70+ AR, and it won't cost you very much. In fact you can probably push it to near 200 strength.
Gloves: I don't think you really need the 3 piece bonus, this piece is largely expendable. You should be shooting for a pair of strength trifectas. Get as much IAS, CC and CD as you can. If you have to make a sacrifice, try not to do it on IAS.
In terms of weapons, you first need to understand your break points. You're currently sitting at 2.263 / 2.117 and this can fairly easily be fixed and the difference to your damage would be significant.

Oh and don't get a 2hand, you don't have nearly enough IAS for it. It simply won't work very well for your current gear level.
Get high vit Inna's, vit rolls higher than str here so take advantage of it. You can replace the strength you lose here by flipping your vit gems to str gems.
You can make a big difference with the budget you have there so hopefully this puts you in the right direction.
