I think we should sell all these items using the guidelines Gwynfrid gave above.
All other items should either be claimed and equipped (as has been discussed with weapons - including the special arrows - and the scarab shield) or sold via auction in the hopes of getting more for them.
Vershab will take the MW Longspear, just in case.
Is a Wand of Cure Light Wounds (for our use) available? This would cost us 750 GP (standard), allowing us over 300 GP to give to Lehasti's parents and retain over 550 GP (from the ancient coinage) for the purchase of consumables.
Vershab would strongly push for the purchase of several scrolls for utility purposes should the circumstances for their use occur.
