Well several things are off.
For instance if that Dire bear was grappling Claire all Lidda's attacks would have been Sneak attacks. Losing your dex bonus is a consequence of grabbling. She would also face a chance of hitting Claire. Another consequence of grappling.
As already mentioned the Dire bear gets an automatic chance of grappling if it hits with a claw attack. It can take a -20 penalty in order not to be treated as grappled itself.
Casting Summon monster is a full round action, so the polar bear won't arrive until just before Hennets next action.
You don't crit with an 18 even with improved critical and a bow. The bow would have a threat range of 19-20*3. And when you roll damage for a critical you roll all the dice instead of multiplying 1 dice + modifiers by three.
The Dire bear would get AOO against Lidda if it wasn't grappling. It has a reach of 10 ft.
Anyway this fights ends as soon as Hennet ends it. A good start would be Web to calm things down (and keep people from attacking) followed by Cone of cold (man he has some lousy feats. Both combat casting and Skill focus (concentration) are such bad feats that I have never seen anyone seriously contemplating choosing them).
