As Doula suggested,know your school.
If they are a culturally diverse school,be prepared to understand the variety of cultures and mores of the varying groups.
I think the only questions that I would ask would be in response to what your interviewer would ask.
I think being honest and open has always worked for me in an interview.They know you are nervous.
Just be yourself.Know that you will be a good teacher.I assume you have had an internship in teaching,you may want to discuss how that went,if the opportunity arises.
You might ask about classroom size,how many students would you need to plan for.Will you have a T.A?
There have been many cutbacks in schools and you may discuss how that has impacted them.
I would let your interviewer carry the ball.
I found a link you may find helpful.
I am a retired teacher and I come from a family of teachers (4 in all)and I applaud your decision.
