Zamos' setup is an exemplary one to follow. You want the t2 3 set effect combined with the t3 4 set effect.
You can take a look at my 60 hunter in my link, but it's the same setup, at least, until I get my helm (He might be logged off in pve set, just a heads up!)!
For enchants I'd suggest either Versatility or Multistrike. Versatility will be more useful if you don't have heals, while MS will be best combined with a healer. Other than ring, cloak, and neck enchants, stick to Agility or Attack Power. If you aren't comfortable with a lower amount of health, grab some Stam somewhere.
