Need Some advice/tips for my first date tomorrow.?

Im 14 and I just got a date with this really hot girl and her personality fits mine PERFECT. She likes to play black ops, fallout, games on ps3, etc. I kno that im not supposed to say anything stupid like farting and immature crap like that but i want just some tips. Also im pretty sure she'll try to kiss me and i never kissed before and i would like some advice with that also. Thanks.
