The Bladesinger and Duelist give Int bonus to AC. I think they are slightly different in how they do it. The Bladesinger has a custom spell list.
The Spellsword reduces the Arcane Failure for armor and gives +1 caster level every even level. Having gone as far as you have with Wizard, you are better off with Spellsword than Bladesinger.
If the Monk doesn't already have Bracers of Armor (they should be now), you might want to take Mage Armor until the monk gets the item. If the Monk doesn't have a Wis boost item, either you or the cleric will want to use that instead of Dex boost on the Monk.
A double-empowered enhancer (Bull's Strength, Cat's Grace, etc) can give you a higher ability score than an item. It takes a 6th level spell slot, but it is something worth considering.
There are a few spells (Dismissal, Transmute Rock to Mud, Remove Curse, etc) that you will only want to carry on scrolls. They aren't going to be used often enough to be worth while.
Beyond this, you're going to have to wing it or find someone who has taken a spellcaster into epic levels.
Good luck.
