Well, first thing first.
The lore and legend quest items are items found on the corpse of the mobs (such as the orc ear and orc eye for the lore and legend: orc quest) so you won't get any messages telling you you found a quest item or not.
The tortured souls in the commonlands near the nektulos station count as ghosts, managed to get 5 of the items but sadly had to make room in my bank so i destroyed them.
You might have to kill hundreds of ghosts until you manage to get all of the items, i know since i've looked the orc quest parts for a couple of days now and still haven't gotten all the parts.
You can also check the broker for the parts if you don't have the patience to kill the mobs yourself.
Hope this helps and good luck with the quest
