I had a consult with a neonatal doc, which I found unhelpful. He wasn't very personable and just ran through a bunch of possible complications and statistics, which I wasn't in a place to deal with. I think the information that you find helpful really depends on your personality, so it's worth thinking about what you want before you meet with anyone. For some people all info is power, for me I really didn't want to think about complications that might or might not happen. It sounds like you already have specific questions, which is great-you might also want to make sure that you have someone else with you when you meet with the doc so that one of you can take notes.
Stuff I would ask:
1) How can you communicate with the doctors. In our NICU a lot of communication happened through the nurses, which was fine most of the time. Sometimes I felt like different nurses told me different things, or they didn't give a complete explanation. Also the nurses sometimes presented things as absolute policy, while the doctors were more willing to make exceptions. I could sit in on rounds for my baby or schedule a meeting with the doctors as I felt necessary.
2) I would ask to talk to the charge nurse or NICU social worker about the NICU policies-for example what is the visitation policy, how will they contact you if they need you, do they offer any extras or support services (we got 2 free parking passes), do they assign primary nurses, can you request a particular nurse.
3) Pumping and breastfeeding (if you plan to do so). Are they set up so that you can pump at bedside, where can you pump, will the LC work with you in the NICU, how do you get in touch with the LCs, when can you start practice breastfeeding.
4) We used donor blood in the NICU, but if that is something you are concerned about, you might ask if someone in the family can donate and how long the screening process will take.
Good luck, I hope that baby stays in as long as possible!
