The quick start guide in my sig should be useful. Basically you want a wand/offhand combo, and use the highest ilvl of the proper armor type (no cosmetic items like mist piercing goggles).
Using all cloth gets you a 5% int bonus. A wand will be ~6% additional stats for your stay template. Increasing ilvl will only get you a few extra stats (0.1% for each equipped average ilvl above 24).
