Job Interview Followup?

I had a phone interview last week, and was asked to come in for a face to face. I went in on tuesday and met with the whole dept which i wasnt expecting. I asked when they were looking to hire someone and the woman who brought me in laughed and said, when you can you start? then she said, no really when can you start. I said i'd have to give 2 weeks notice. End of interview she says, ok great well we should know in a week. That night i received an email from her and she told me she'd like me to meet with HR, said they would be reaching out to me and then she asked for my references. I wrote back thanking her for the interview, said i'd be happy to meet with HR and gave my references. this was yesterday morning and I've received no reply. I was thinkng she'd thank me for the references? Not sure what to think now. but it sounds likes were good?
