Setekh: Exactly. The only problem with High School Spanish (mine at least, for the most) is you hardly get any of the culture as much you are baby sat. God, our educational system sucks. But I'm expecting more from a College than I am from a highschool.
Anyway, in that respect, Japanese is probably the culture I know the least about, and even less how to speak in.
Pyro: Russian or Japanese would probably be my highest scoring languages in terms of culture, usefulness, and my personal interest. I would be most interested in taking latin the most, (although Russian is a close second) but it doesn't have a lot of practical use other than being l33t and studying up on things.
Beat: German would deffinitely be the easiest. I have a friend taking it too, so that helps. I'll probably talk to him about this a bit too.
Kas: The cool thing about this is, it would be an 'extra' class so to speak, so it would be a great time for me to take something like Latin, because I can still take one or two more languages before I go off into the world in 6 or whatever years.
Lib:

See Kas.
Snipes: Yeah, that would be my choice, hands down, if they had it. But it's a Community College, and Arabic (Farsi, whatever) is rather specialised I think, so it's not available at the time being.
Corsair: Chinese would make sense with the current world politcal situation. BTW, we need to talk. Got IM?
