<human>: Could you distill the essence of the text into 1-3 sentences?

I have never asked a girl out in my life (only ever told one I liked her) before and I don't have many people I am comfortable talking about it so here goes.

I really like this girl she is cute, funny, and smart. I have 3 classes with her a week one of these being a 3 hour lab where we are at the same table. 

I have no idea if she has a boyfriend already and she doesn't have a facebook so no easy way to find out. Basically I would like some advice on what to say and how to not be nervous about it. 

I was thinking about asking her to grab a coffee. Is that good? 

Then if she says yes what do I talk about on the date?
