Don't buy diapers or clothes in NB size, they will not fit in a week. You need a stroller, a sling will help them a lot because they love to be attached to their parents' chest, so you can put your baby in one of those and be able to do your chores in peace because you will have your hands free, it's a win-win, happy baby, happy parents. I like playpens more than cribs, they are more useful in my experience.
