I grinded Bone Armor Chest Plates. 300 Gen. Craft XP or so per single chest plate. Got me through to Novice Weaponsmith, and after dropping Novice Weaponsmith for resource reasons, got me through to Novice Tailor.
Unarmed 1-4 should be easy. I did it ungrouped on Corellia, South of Coronet. I beat up on random spawns of Scavenger Rats, Durni, Vynock, Gubber, and others. Level 4 of unarmed was slow, but I got through it within a few days.
