Here's a Final Fantasy XIV: A Realm Reborn crafting XP guide by Capkin that shows you how to get a lot of experience points while crafting.
Note: Another very good source of crafting xp is to hold off until you have lvl 20 with your first class. Then you can purchase Engineering Manuals from your Grand Company. These boost your crafting experience points with +20,000 XP per use.
