Jasra, on that mission for the gree where you have to travel around, the only one that may give you some problems is voss. When you are going there yell (if I am on) and I will go with you. Otherwise, on your sawbones, stealth in unstealth by starting coversation, then after convesation hit escape and run away. Leyn'a and Mar'ina I just killed the droids, with Brem I had to resort to heroic moments, with Sliv'ilia I did the stealth trick...Way easier. I used that method for all the droids on the other plaents, even though the rest are easy to kill.
On topic: I hate Hoth. Some fun datacrons there though.
