Siella will search each of the goblins to see if any of them have anything on them indicating whether or not this was just a simple raid or banditry setup, and help loot the bodies. Then she will dump the bodies into the pit trap, both to dispose of them, and to expose it so unwary travelers don't get injured, if no one objects to it. She'd make a sign, but she doesn't hae the materials. Any loot will be depsited in the saddlebags of (I think) Caladur's horse for ease of travel and safekeeping, if he's okay with it. I don't think anyone is small-sized, so none of their equipment is usable, save the potion.
