First date??

So me and this girl went fishing a twice but it was with a friend tomorrow were going out just the two of us. My brother in law works with her and he said she asked why him and my sister didn't want to go. This made me think that she didn't want just the two of us to go. I didn't text her today to see if she would text me and she did we talked about tomorrow I told her I would pick her up she said sounds good and she was excited. Is this the first date? Im kind of new to all of this stuff. Should I ask her about her ex I know both of our last relationships ended the same way but she never told me. what else should we talk about? When I take her home should I walk her up to her door? just a few question I had any advice will help a lot.
