You can try talking to every npc for quests, or you can see which ones hail you as you walk by. You can also go
here and do the advance search on the side and look things up by zone.
You do not need all the appII they dont really make a huge difference, and it allows you to save some money for appIV or adepts. But again you dont have to upgrade everything, just what you use often.
If you want to start crafting right away you can, but you can also wait till later when you have more resources to start, there is not set level to start.
