A spiked chain isn't as good for a monk as it is for most other classes. Not to say that it's not good for a monk but a large benefit of a spiked chain is that it is a reach weapon that also threatens adjacent. A monk already has adjacent covered with Improved Unarmed strike (and it does more damage than a spiked chain too). I would save yourself the feat on Exotic Weapon Proficiency and instead use a Reach/Trip weapon like a Guisarme. Its great to trip people with an AoO and then 5ft step and flurry with your unarmed strike on your turn while they are prone and taking that -4AC.
Are Psionics allowed?? Psychic Warrior would give martial weapon proficiency, powers like Expansion, Hustle, Psionic Lions Charge, and more, also you get bonus feats like a Fighter in case you still want that spiked chain.
Cleric or Ranger are also good. Anything that gets you a spell list so you can use items like wands and scrolls. A monk can use any part of there body for there unarmed strikes, not just punches, so you can have a wand or scroll in each hand and it will not impair your fighting ability at all.
