Preparing for breastfeeding/bottlefeeding uk

I am not sure how I want to feed. I think I am going to give breastfeeding a try and see what happens so I feel like I need to prepare for both breatfeeding and bottle feeding. If I do breastfeed I feel like it might not be for long. Should I get things like a breastpump and bottles/steriliser/formula etc ready straight away?
