Who is in the room when you give birth

My husband is extremely sensitive to blood and medical procedures. His father and grandfather were too, as in they tend to pass out over visible blood or needles. It's an actual medical/ mental condition that is more common in men then women. He has declined to be in the room when I give birth or have a c section. I'm in agreement with this and understand that he has no control over this. He said he will be there every second before and after the moments of birth. We have been together for 14 years and I don't want to spoil the birth of our first for him by him becoming very ill during this magical and gory moment.

My best friend is going to be in the room holding my hand as i have for three of her four children. but my mom and MIL have hinted they would like to be there. I'm fine having them in the room but is it okay for me to ask them to not involve themselves with the doctors during the birth. My mom tends to be a little stressed and bitchy when things aren't going the way she thinks they should, and my MIL was the head of maternity nurses at a city hospital when she was much younger (30 years ago) and likes to offer "advice".

Who is going to be in your delivery room and how do you plan on making sure people are behaving themselves at a time that you shouldn't have to think about any of this crap?
