Hang around the food - firstly, you're not the 'wierdo at the back' any more (and you can occupy yourself by eating), and secondly lots of other people do that so there's reasonable chance of getting into a conversation.
I always end up doing this because I think I will look semi-normal, but I always end up eating too much, like literally non-stop eating, which backfires and makes me look super weird anyway.
The good thing, is you already know who you need to talk to. You said your goal is letters of recommendation and assistantships, so you know to focus on professors. I would say, just walk up and tell them you're making the rounds trying to meet the professors and learn what classes they teach. You can maybe tell them a little about what interests you in linguistics and then move on to the next one. I would try to spend just a few minutes with each one and then make an early exit. (Actually, I would probably even tell a white lie and say I had somewhere to be, so I could get through the conversations quickly).
