I'm not sure if there are ludi quests that early, check the website, but I highly doubt it.
Charms of the undead are at the ant tunnel (kill undead mushrooms) and Necki Skins are from Jr Necki's, you can find some in the hidden street from Kerning (where the PQ is, middle 'drain' type thing.
All this can be found on hidden-street.net though.
