What crafting class should I pick up first?

I would like to add to what Frizze posted; I would advise leveling Botany and Mining alongside Culanary. You can get most of the non-crafted materials for Culanary from Botany, but Mining provides the various shards that all crafts use. You don't need to take mining very high at first, but as your crafting progresses you will need to bring mining up in Levels. No matter what crafting class you go with leveling Mining and Botany alongside side it will save you a lot of gil and headaches later on.
