What to do in SW:TOR for just 3 days?

rodrigoandrade writes: I've been invited to participate in the beta testing program for SW:TOR. However, EA's giving out 3-day passes to most testers. A few people are receiving passes for longer periods.

Mine will be from Friday 5am through Monday 12am (CST) (i.e. Sunday evening)

Since it's a frakking 10GB download (amost 2GB for video alone) I'll use for only 3 days, I'd like to make the most out of it. If you're an experienced beta tester, please post some tips travel-guide style on what I should do, quests I should take, places to visit, etc. TYIA. May the Force be with you!
