I am in a similar position myself. I am considered high risk, and a hospital birth is my only option (since I'm not up for an unassisted birth). Are there any birth centers around you? If so, that might work great. Or could you see a midwife instead of an OB? That would be my next choice. Here are a few of the things I'm doing to try to make the best of my hospital birth...
I am spending a considerable amount of time doing research on common interventions (so that when someone says "you need this because" I will not be frightened into an intervention I don't need.) LOVED Ina May's Guide to Childbirth, and the chapter on labor and birth in Christiane Northrup's Mother Daughter Wisdom.
I wrote a birth plan and revise it as I learn more, and to make it as personal as possible (e.g., originally, I said I wanted perineal massage instead of an episiotomy. Now I realize I don't want either.) I showed it to my OB to judge her reaction. At this point, I am mostly convinced that I need to switch to another OB and another hospital.
I found out who in my area understands and supports natural birth (mamas, Bradley instructors, doulas, CPM) to get their advice and suggestions for midwives, OBs, hospitals, etc.
I had a hospital tour and asked a lot of questions about their routine interventions (not all of which were answered truthfully.)
I made arrangements for a meeting with the head of NICU to find out their protocol for taking babies from mamas after birth. I'll show him my birth plan, too.
I hired a doula, and dh and I are taking the Bradley class.
I plan to spend as much of my labor at home as possible.
It was suggested to me that I modify the hospitals std consent form to say I will not allow xyz interventions. I don't think I have the fight in me to do that. Check out my thread here about whether a hospital has to follow my birthplan. There's a link with legal info about modifying consent forms.

Do you have options for OBs? If you had one you trusted and had a good rapport with, you could find out exactly what you'll be up against when you are admitted.
Best wishes to you. I'll look forward to reading other suggestions...
