Re: HM's proposal for expenditures, I recommend replacing the two Stabilizes with one potion of CLW. My logic is just that we're most likely to use the potion if both of our wand wielders are down or unavailable. In the event that they are both down, it is absolutely critical we get one of them up rather than stabilizing two people (whether the CLW does that or not is chancy, but it's something).
Re: Carrying equipment, Kara is a poor pack mule but a good shot. She should probably have one of the splash weapons. I also think she's a good choice to carry a CLW or Stabilize; if the fight goes this far south, she's probably out of spells and low on acid ammo, which means there won't be much better for her to do.
