Breastfeeding and bottles

This is my second baby but first time breastfeeding. I'm due on the 29th of this month and still unsure of everything I need to know or where to go for advice. Also I have yet to buy any bottles but I do want him to learn to eat from both for when I am away and also bonding with his daddy. What type of bottle seems to work best for breastfed babies? Should I buy bottles now? Or wait? Also when should I introduce the bottle? And basically any other breast feeding advice you have for me is welcomed. I'm so nervous about it but it's something I really want to do that I wish I'd have done with my first..
