I'd agree with Treat Injury being the most useful skill to take. As for languages, um, not sure, ask the DM? Huttese is really useful as a trade language, but if you don't also want to take it maybe Yuzhan Vong? That might be handy if we run into some. Otherwise pick a race you really want to be able to talk to. For instance I took Cheunh because Chiss are sexy, awesome and I'd rather not be shot by them.
Also a question for the DM, this game is being gathered on Elliquiy, but what is the expected sexual content in the game? None, Background, Low, High? Thanks!
