You can get your craftinig skills at lvl1 if you make the trip to the fleet...take three gathering skills and change one later.
However be very careful that you select the right ones as you can not drop or swap them until after you get your companion as the crewskill button will not work.
I picked the wrong ones and now must wait until lvl10 to change them. Also as a trooper with the slicing skill I found nothing to slice on Ord Mantell, nothing at all.
