HELP!!! 1 week to prepare

It's a loooong story but my boyfriend and I are about to have his 2 month old son come live with us in NYC. We are VERY excited and think he is a blessing but we are also very scared. We have about 1 week to prepare so we will be learning as we go along. We have already visited him on two separate occasions so we have some idea of his current schedule etc..but would love to hear any tips/advice from nyc parents on getting around in taxis, nannies, classes, strollers, anything really. Thank you!!!! PS- We live in the west village in a small 1 br so creating a sleep space for him is a big challenge right now. Any preferences in bassinets/baby beds?
