long breastfeeding question please give some advice

Bethany
Okay so I'm due in 24 days and I REALLY want to exclusively breastfeed. I just don't really know how it all works. 
1. Do I take my pump to the hospital with me?
2. Do I pump in between feedings and if so will it affect me?
3. Can I pump on my left side at the same time I'm feeding on my right side or vise versa?
4. When do I start giving my baby a bottle with milk in it to assure she'll take it for when she goes to day care? 
I know for sure I'm going back to work at least 10 weeks after baby girl is born so I'm gonna need a stash for that. I will be pumping at work also.
