What Questions Should I Ask an ENT Before Surgery on my Nose?

I'm planning to have surgery with an ENT doctor next month. He is fixing my deviated septum, my fractured nose (closed) and turbinate hyper trophy. He also said he would be shaving down the bump on my nose and when I asked him if he could make my nose have a slope, he said yes, that's reasonable. Before I commit to paying my surgery, what specific questions should I ask him? He seems like a great doctor who knows his stuff but I want to make sure I'm making the right decision. Thanks!
