Try and get them all for now, they changed the xp so its really fast to 50. Vendors sell all mats you need until lvl15, after which you will need gathering jobs or marketboard.

As a Archer you will want Carpenter and Leatherworker as it makes most of your gear.

Again i would do them all at same time as they share clothes and will save you money, especially when you get to repair your own gear.
