The gem on weapon depends on your other gear. The correct gem can be figured by simulating on d3up.com. Marq ruby was a clear winner for me with 7k dps over marq emerald.
I would upgrade pants to blackthornes and bracers to lacuni's. Or inna's pants and crafted bracers. I think blackthorne/lacuni is better because the ehp from 12%life blackthornes cannot be replaced by inna's/rare bracers. Inna's pants are very limited in rolls while lacuni's can roll a large variety of stats.
You will need more mana regen to farm high mps efficiently. 4 piece zuni, mana regen zuni vision, and mana regen/bear reduction mojo. I would get at least 2 out of the 3 of these for mana.
Also I would ditch the echoing fury because the fear proc is counter productive and will slow you down. Go for a lifesteal weapon. Even if you lose dps, lifesteal will keep you alive.
