Finally met a girl I had a crush on. Now what?

[me]

I had a crush on this girl for a long time, but I never talked to her. She works with one of my friends and he took me to a party she was at. I met her and we talked a little bit, but all of us were pretty messed up so we didn't talk too much. I know she's single or if she's taken he wasn't at the party.

Anyways I'm just happy I know her a little bit now but what should I do next? Should I add her on facebook, follow her on twitter or instagram? I'm really bad with these types of things, but I want this to maybe work out. I could also show up to her work and talk to her when she's working, but the problem is I don't know when she does work or will be able to talk while she's working. What should I do? Thanks

If it helps, I'm a junior in high school.
