As kev said be yourself, there is nothing worse than telling her you drive F1 cars at weekends and she finds out you have a scallextric set at home.

Be pollite, sesitive, a little witty but not at her or about her, always listen even if she butts in, and as Kev said pay for everything, I know we are in the modern day but women still think we should pay.....

Others than that good luck....
