The Solid Crystal Leg Shaft's drop of glassweb spiders. I found its easier to just do white DPS (Do NOT use any special moves like sinister strike just plain regular attacks. and they drop about 90% of the time that way for me. using abilitys the drop rate is lowered alot. Im not sure why but i've seen quests like that before and this is one of them.

The Ledger drops on the ground by the outhouse. If you miss it right click the outhouse again and ask to see it he will slide it back under the door.
