Excellent pictures!

I think the claw damage *replaces* the 1d4+4 nonlethal damage (IF the monster has improved grap). In Part 4 of "all about grappling" from WotC it says (under improved grap):
> Each successful grapple check the attacker makes during successive

The "(This works just like making a grapple check to deal damage.)" - part lead me to the conclusion that you don't get the size-dependent damage in addition.
I agree with the constriction damage.
