Love / Advice wanted: meeting Polish girl for the first time [19]

I'm soon going to be fortunate enough to meet in person for the first time a Polish girl that I've recently been getting to know online, and would appreciate advice on the correct etiquette for our first meeting.

Should I shake hands with her, kiss her hand, kiss her on one or both cheeks or kiss her on the lips?

I don't want to come across as too formal or reserved, or too presumptuous or familiar, so your advice would be appreciated :-).
