1) Some DMs rule that the two-weapon fighting penalties last until your next attack, just like the penalties from Power Attack or Expertise. This is unclear in the PHB but unlike PA or Exp it does not specifically say 'on all attacks until the next round'.
2) You get only a single attack for an AoO - you never get to use multiple weapons.
3) The rulebook does not explicitly state that you can use your off-hand weapon when making the AoO, but I can see no reason why not to allow it.
Then again, some people think my own interpretations of 2WF are unreasonable (I let you divide up the iterative attacks between the weapons as you wish, as long as you don't use the same one for two attacks at the same bonus), so take any or all of 3) with a grain of salt.
