Hey! So, in general I feel like I've done well in gearing my WD. I just farm MP8, but in general I don't know where to go for my next upgrade. Any thoughts?
If I want to be faster I switch out my pants for Inna's and I'm at 190k DPS, but I have to dial down to MP7.
A few thoughts for you. Inna's pants will give you some DPS and 12% MS, but you take a big hit to EHP so most Docs don't consider them a good alternative. If you want to improve your pants look for 150+ int and vitality, 70 allres, two sockets and if you can get it +armor.
If you don't already use D3up.com, I highly recommend it as a very good EHP/mitigation/DPS/gear calculator.
When shopping for new items, look at the tooltip comparison and try to get 3 green numbers (so increased DPS, increased HP, and increased Protection). Remember that attack speed has to be managed, so figure out how much you want (if any) before you shop.
Other than those tips I would shoot for 550 allres, 4000+ armor, 65K + HP as a baseline to get your defenses up for MP10. Also, and at the same time, push your DPS as high as you can (again while managing attack speed).
The last advice I would give you is if you want to be a student of CoB, see PaulNG's CoB guide in the Builds and Guides sticky at the top of the forum.
