Well, I would have called her that nite a little after she got off, told her that there wasnt too many parties going on but she should come over and hang out and party with you
I give this as advice on what I would do so um.... dont take it
It seems to me like she is interested in you, but after what you posted a group event would work out best for you to get to know her and then show interest in her and ask her out maybe at the end of the event or on a later phone call...
If you know of a party, concert, (bar i know...)
that or go w/ the no party... want to go.... w/ me
again I'll copy and paste my previous sentence
