Do and don't in Azerbaijan

I'm a Southamerican guy thinking of going for a short holiday to Azerbaijan  to comply a promise I've made to an Azeri girl I've met in a short encounter in US. Actually I don't know nothing about the Eurasian culture neither how the life and the people are there. I lived in many countries except in that region of the world, I just knew a bit from my friend, but not enough. So, I would like to know what to do and what not to do, especially with the girls and their parents. I don't know if a girl is single I can invite her to go to have a dinner, to the cinema or for a walk without breaking any rule that maybe is highly rooted in the Muslim culture. I don't know what is the impression the azeris have about people from other cultures and religions. I guess that maybe there are not many spanish speaking expats there.
