Gyno questions

I'm about to go see my gyno for a yearly check up and pap. My husband and I are also thinking of ttc soon, if everything is ok. 
Are there any important questions I should be asking my gyno. 
I've made a list and so far I've come up with:
Checking hormonal and thyroid levels 
Blood tests for both me n husband
Any mandatory check ups my husband n I need to do?
What is difference between pre natals and folic acid and which is more important and when to start taking them? 
We don't have any children yet, obviously :)
Thanks guys!
