House party

Right, I feel if I am going to get the most out of this I need to step back from myself, be willing to take input on things that are routine to me.
Saturday night I am going to a small house party, about 20 people in a flat.
Aside from the normal HB's who always attend parties, there is an HB8 I met at a party a few weeks ago. I n-closed, she added me on facebook and we have been chatting since. I would have done more than n-close, but I was far far far to drunk to do anthing cognitive
So, I am leaving this question vague on purpose, what do you suggest I do until the party and at the party to get the most success?
