I suggest adding (for Imperials/Republic PC's) kits which you receive once a reset from your faction quartermaster. These would essentially restock some basic supplies. DM's could also restock the kit after an event. Higher ranked characters receive more in their kit, perhaps even pay to go along with it, while new characters receive the bare basics, or even nothing at all. All items in the kit should be marked plot so that they cannot be sold to merchants.
-Assault Specialist: Grenades, Personal Shield Generator
-Melee Specialist: Bacta vials, stimulants (Strength, Dexterity, Constitution)
-Medical Specialist: Healer's Kits, Adrenaline
-Tech Specialists: Auto-turrets, repair kits, grenades, rocket launcher
-Pilot Specialist: Single use summon which will make a basic ship follow you around in space as a henchman.
