What length of JR Pass do I need?

My itinerary is below. I’m thinking we ca start the 21 day pass on 29th March for all our travel until leaving Japan on 17th April. But what would I need to get to Tokyo from the airport and to get around Tokyo for the dates 24th March to 29th? I am confused about the additional cards, the PASMO and Suica card, will we need one? HELP!
