For 2v2 900 -1k is plenty for most comps, vs heavy cc comps can go a little higher like 1100-1200 Anything above that your gonna have low dmg output.
Weapon is fine, trinkets are ok, but generally you want attackpower trinkets, so your deathcoils dots etc are more effective, arp is more of a pve stat for unholy, and going with enough to make a difference 40% plus, you'll be more squishy.
