Peppers, just have to say I feel for you on the out on training thing... my husband was in Iraq when our youngest was born.
You CAN tell the hospital you only want certain visitors and at certain times if you so choose and your sister becomes that big of an issue. I did that with my last as I didn't want people coming and visiting me while my husband was gone and trying to "sympathize" that he was gone, plus at that point I was about to the point of having restraining orders against his family. Thank all that is holy they pulled their heads out of their butts since then.
On the circ thing... all three of my boys were done. It did not interfere with bonding or nursing. As for the drugs, I didn't notice any problems with bonding with having the pain killers... Lol except for the little while I was on morphine after my youngest (had a tubal within four hours of delivery... I apparently held a conversation with a lamp when I got back to my room husband was going to have a vasectomy if he hadn't of been deployed. He wasn't happy with me having a tubal since it was more invasive than his surgery would have been). I do have to say in my case I the epidurals helped... A LOT. I wasn't progressing with labor with any of them due to being to tense and in pain due to all the contractions being felt in my back (and I have scoliosis), once I my water had broken and they were able to give the epidurals, I was able to relax and was dilated quickly.
I do hope that you can follow your birth plan, but do remember those are there IF you end up wanting or needing them. Don't have to use them.
Okay now that I have rambled enough I think I will go wander back to my normal forum sections
