From the point of view of crafting things you can use yourself, either Artifice (things for your lightsaber to increase your stats) or Synthweaving (armor) would be best for a Warrior.
As for the gear, the main thing you'll be wanting as a DPS Warrior is gonna be Strength. Endurance and other stats will come along with that, and then just decide what you want on it.
This comes from a limited understanding of Warrior/Knight classes, that's just the basis of what I know from my own juggernaut being level 16. I don't claim to know a lot, but I hope this helps
