I am pretty new to D3, just started playing a couple months ago. I just recently reached level 60 and inferno mode. I did a little bit of research about what gear was good, and the stats, then bought within my budget. I wanted to do a CMWW build, but I think I am too poor for that atm.
Doesn't look too bad. I'd spec Archon and go for either act 3 MP0 (Keep Depths 2) or, if it works at similar speed the "regular" act 1 route (Leorics Manor, Festering Woods til 5 stacks, then clear Fields of Misery, Weeping Hollow) on MP1 (increase if you feel like it, check out the thread by Loroese with dps/ehp figures).
For gear, I'd look for more crit and crit damage first to improve that Archon farming, attack speed is very important for CMWW, but it doesn't increase dps that much and you'll eventually have different gear sets for both specs anyway.
