I value looks as much as performance so my gear may seem different to some:

Weapon 1: Electrum scepter +1 /w int materia and Gridanian square shield
Weapon 2: Garuda's Van
Head: Electrum monocle +1 /w int materia
Body: Militia Robe or Wizard's Coat (looks a lot better)
Hands: Mage's halfgloves (if you need more macc) or Boarskin ringbands of storm +1 /w mcrit materia
Waist: Raptorskin satchel belt /w -enmity materia or Serpent sergeant's belt
Legs: Woolen tights /w int materia (loresmen preferred over wise man's but more expensive)
Feet: Mahogany pattens /w matt materia or Wizard's crakows
Neck: Mage's Choker (for more macc and crit) or Spinel choker +1
Ears: Mage's earrings
Wrists: Zircon Bracelet +1
Rings: Black pearl rings +1 or Zircon rings +1

Those I listed should be quite readily attainable apart from Garuda's Van and Militia robe. Aim for double melds especially when doing int.

I would aim for the following stats (unbuffed):
460+ matt
450+ macc
360+ int
-20 enmity

Those are you main damage-based stats. Some hp gear wouldn't hurt as well to help you survive big attacks and slightly better conversions ^_^

And btw, you'll be staring at your character for many hours, might as well make it look good too...
