PHB only?
Sorcerer, Cha/Dex/Whatever, full (light) armor + Still spell. If he's human, take another feat and get him a weapon of your choice.
Sure, you won't be able to still your 1st level spells at 1st level, but that ASF isn't that severe. I ran a 1st level human Sorcerer in Scale Mail and NO Still Spell and only lost one spell to ASF. (Yes, I used stuff from non-PHB sources, but none of that affected his spell failure chances.)
Or, as I'm sure someone will point out, simply play a Paladin or Cleric and call him a monk. Wear (light) armor, use IUC and kick ass. No ASF, you'll be able to buff yourself into ridiculousness, and you'll be at least as effective as a Monk...until you're more effective.
