Formula & bottles!!!!! Help please lol

So I'm a soon to be FTM & I'm starting to get ready for my sweetheart's arrival. I do plan to breastfeed but I'm almost certain that I will have to supplement with formula at times due to being an elementary teacher with limited pumping opportunities so my question is what is (in your opinion) the best formula to supplement for a breast fed baby?? Also what about bottles?? What are your favorites??
