First Date???????

Hey Guys, I met this girl over myspace and she was very religious like me and she invited me to come to her church almost three weeks ago. We have been hanging out since then and I had easter with her and her family which was great. I asked her to a movie on sunday and she said yes. Yesterday I told her what time we should go to see if it worked for her and she said she thought so. I apologized for bringig the movie up cause hate brining things up over and over........But anyway I have not been on a date in a long long time and I am really into this girl, she is everything I am exactly looking for. I am a really shy guy and sometimes I freeze up and dont know what to say. Do any of you have any tips on conversation topics or any tips at all for the first date? Thanks in advanced and hope you all had a good easter. god bless
