Which Passes should I buy

Hi, I will be travelling to Japan this coming mid dec (spending about 10 days), as this is the 1st time travelling to Japan with family (3 kids-4,8 and 11yrs). I would like to check which rail pass is suitable for my trip as i will be flying in from Haneda Airport in 0530am and leave on 24 Dec from Nagrita Airport. My itinerary will be such:

Day 1: Reach Haneda Airport and go straight to Gala Yuzawa spent a 3days 2 night
Day 2: Gala Yuzawa
Day 3: Back from Gala Yuzawa to Tokyo (looking for apartment in Shinjuku area),
Day 4: Disneyland
Day 5: Disney Sea
Day 6: A day trip to (Nissan Cup noodle museum) in Yokohama
Day 7-9: Maybe Hakone or just stay in Tokyo and explore museum
Day 10: Back to Singapore

I am open to all suggested Itinanery as this is a 1st visit to Japan, I hope the trip will not be too tire for the kids
Plus I am quite confuse about the JR pass and JR East pass. Please advice me on which passes should I use or should I get a normal Suica Card.
