I think only get a pump if you either have low supply issues or want to pump to have some 'spare' in the freezer to bottle feed when you're out. Most women I know with good supply find they can hand-express if they get uncomfortable.
I was also going to say, don't feel bad if BFing isn't the amazing bonding experience so many women find it to be. Personally, I just felt like a milking cow during feed times. I felt like I was bonding so much more with DD when we'd just have little cuddles and she'd let out a little sigh - she was happy and she wanted for nothing.
