I concur with our illustrious mod. My general strategy (if I'm not in a hurry and I have a reasonable number of characters; 4+) is to take back all weapons worth more than 5 GP. Essentially, longsword and better. I leave axes, daggers, and especially the ultra heavy maces and flails, unless they are high quality.

A little financial flexibility goes a long way. You can pick up the bardic horn, better armour, spells, potions, etc. if you have that extra couple thousand cash.

My strategy for this area is to draw the skeleton archers with one character, unstealthed. You can draw the archers back to the entry foyer - if the rest of your characters stand on either side of the door, the archers have no angle to hit you, walk right in, and get clobbered. If the archers don't walk all the way in, they usually come close enough that you can charge out and get them into melee before they can get off more than one shot.
