The
http://wiki.project1999.com/Player%20Guides page has guides for each starting city that include all quests like that (most aren't as simple/easy/rewarding as gnoll fangs though) ...
... or at least it does for three cities. The rest ... anyone want to step up?

Also the wiki has at least one "repeatable quests" or "good quests by class" or something like that page, but I can't remember it and the wiki is down ATM.
