Yeah, if you have high Battle Fatigue, your combat effectiveness goes out the window. Simply visit a popular cantina (Coronet, Mos Eisley, Dant. Trade Outpost) and watch a dancer/listen to a musician, or both. They'll get rid of your battle fatigue and even give you a 10% exp bonus for 3 hours.
Wounds require either finding a doc to heal 'em (most, like me, will do it for free. it's not a problem). Otherwise, go AFK in a med center somewhere for a while.
Hope this helps.
