Try2Handing covered what you need to know about Wits, but I spotted something else.
You have way too much CON into everyone. Your primary defense is armor, and you are not going to need that much CON.
Your cleric is built wrong. Don't split points between STR and INT. You can only do one type of damage at a time, so splitting your points effectively halves your damage. Lose the points into INT.
