Congratulations on your pregnancy!
I FF from birth and DS did best with regular Similac and Dr. Brown's bottles. We tried Enfamil and Born Free and Avent bottles but they all made him gassy.
I wouldn't stock up on bottles or formula though. You never know what that LO will tolerate best. I'd start with one kind of formula (might be easiest to try whatever LO will have in the hospital after he or she is born) and see how it goes. It takes a week or so to see how they adjust to a formula switch.
As for bottles, get 2 or 3 of a couple of different kinds and see what the baby likes best. Then stock up on them.
And don't worry about people throwing "Breast is Best" at you left and right. Everyone has an opinion but it's no one's decision but yours. I got plenty of crap from people for FFing. None of those people bothered to ask why. In my case, breast would have made my child extremely ill so no, it is not best. Even if you don't have a medical reason to choose to FF, that's completely fine. My DS has never had a drop of breast milk and he's completely healthy. My best friend breast fed from birth and her kid is sick every other week and has been since she was a couple of months old. It's not as simple as breast milk being the be all and end all for all babies. Like everything else, it's not a simple straight line from point A to point B.
