First of all you need to relax

She is just a normal girl like the millions out there.
I would act as an alpha male! Decide where to go, make suggestions on what to do, open the door for her, make her follow you while you turn around to see if she is following safe, grab her by the waste to move her if people are passing by her in the club, act a bit chivalrously
Then I would be funny and light and easy going. No compliments necessary at this stage of the relationship except maybe when you see her for the first time and you kiss her hello then through a "you look fantastic" line while spinning her around (maybe I took this too far

)
Well if you look relaxed, keep eye contact, be funny and be mature about everything then you'll be ok!
