Have a few questions about preparing for my little one. :) H

So..... I know i'm going to sound really retarded, and I promise i'm NOT clueless. I just want to be AS PREPARED as I possibly can be.

I'm 19 and pregnant with my first, Bentley John is due on September 24th.

Now into my last trimester and of course have a million and one little questions and concerns that randomly pop in my mind.

1. What should I bring to the hospital 
- FOR ME
- FOR BABY

2. How exactly do I go about choosing a baby doctor 
- This is a little confusing for me, the hospital where I am planning to deliver is a little over an hour away from where I live. So I'm not sure if I should pick a doctor near the hospital just to check the baby out? I'm not sure how i'm going to go about it.

3. How bad does the epidural really help  Does the injection itself hurt  And are women looked down upon for using pain medication for labor instead of having a baby naturally 
- I have a very bad back. I was in a car accident when I was younger and have a few slipped discs, a chip in a bone, a crack in another, and of course being so young, i'm just supposed to manage the pain until i'm older. My doctor doesn't want to do surgery because i'm so young, and shouldn't have back problems. And also, to top it all off; my little Bentley, as of right now at least, is breech. I know he's got plenty of time to turn around but if he doesn't, i've heard it can be a very painful process if they try to turn him. When my mom had my younger twin brothers, the youngest one tried coming out sideways, and she said it was very uncomfortable for her to have him turned, and so she's worried about me during my delivery.

4. Does breastfeeding hurt or destroy your breasts 
-Before I start getting hate replies about being selfish. I plan to pump regardless, I want Bentley to get the very best nutrition that he possibly can. My only concern is how my breasts are going to react to breast feeding. I've heard all sorts of horror stories about breasts being super saggy and pancake-like after breastfeeding. And again, I'm going to pump regardless, i've just heard from others who have breastfed that having the baby actually attach themselves to the nipple can be painful after the pulling, tugging, teething, etc. Just looking for some information, advice and experience on this.

Any additional information about anything, feel free to share stories and experiences too.

Thanks for those who post.
