You can pick up quests in Missionpoint, Which is in Portal Island. You can find where it is by mousing over your minimap while in F2/F3 mode (which you can switch between by hitting F2 and F3, respectively.) If you need help finding out what drops what/Where to find what prey/items, Have a look in our Game Wiki, which you can find under the Home Tab on the forums.
Hope I helped! Have fun, and Welcome to Last Moon!~
