newborn essentials

hi mommies I am 34 weeks now. starting to prep for bb. can you kindly let me know if I actually need these things since I plan to breastfeed exclusively? I heard that bottles can create confusion to bb and they might not latch after so do I really need it? Also since I am a full time housewife most of the time will be w my bb do I need an electric pump? 1. hakaa or electric pump? 2. milk bottles? 3. milk storage bags? 4. steriliser? 5. pacifier?
