Monk / Cler is a bit of a weak character (personal opinion). Monks are only powerful towards the higher levels. By spreading your exp on cleric skills will lessen the monk's martial effectiveness.

Paladin leader is always a good choice. Aura of courage helps as does the ability to "detect evil" (it may no longer be a spell/skill, but it is still in effect.). Also "Holy Avenger" comes to mind.... i still haven't found it....

As others have mentioned, Con 8 for a barbarian is going to be a major problem.... What did he grow up on? Eating grass and berries?

Anyway, whatever your party, it will be fun playing with it. You can always choose a different party the 2nd time round.... Based on comparison with friends; there seems to be lots of different available conversations and outcomes depending on your party.
