In all honesty just level, loot all drops sell all greys, greens, put blues/epics on GTN for a fast selling price AND IF you dont go crazy w/spending at the GTN and Crew missions you can make close to a mil just leveling to 50. My sorc at 50 ended w/866k that was after buying all training as I leveled, buying lvl 25 and 40 speeder and leveling professions.
