It doesn't matter who you are, attending surgeon or "merely" a resident, nurse, or surgical tech... if you are performing patient care and something in the room is distracting you from being able to give your best performance for that patient, you are absolutely within your rights to politely, professionally, request that the distraction cease.
"I need to focus on what I am doing and it would really help if extraneous conversations could be kept to a minimum. I appreciate your help in this. I want to do what is best for our patient."
As long as you keep the focus on the patient, as long as that really is the impulse behind your request, no one has any ground to stand on in arguing the point with you. Internalize that. Those who know how to speak in terms of patient first find that they wield much more power than those who talk about themselves.
As for referring to you by your first name... Some surgeons prefer that, while others prefer their title. Request what you want. Again, professionally, courteously, but firmly. You have every right to be addressed in the way that you prefer. If you know how to insist upon being shown respect without being a jerk about it, you won't have those problems you are concerned about, going forward. Even in ORs with malignant cultures, you decide how you will be treated by what you are willing to tolerate. Always be kind, never retaliate, rise above any pettiness that might be shown toward you, and you will come out ahead every time
