Guidance please!

Hello. I will be making a 14 day trip to Japan with my mother and my daughter. I will be landing in Haneda Airport, will be staying in Tokyo for 4 nights, and then in Kyoto for 3 days ( including a day trip to Nara) and will then head to Osaka for 3 days ( including 1 full day at universal studio). And then want to visit Disney land for 2 days and then catch our flight from Narita Airport from there. I would really appreciate your help if someone can guide me with these things: 1) whether this route is ok or not? If not, can someone guide me with this?
2) what JR pass should I buy? 3) should I include other cities too in my itinerary and whether the daysthat i plan to spend in each city ok/less/ more?

All the help, guidance and suggestion will be highly appreciated.

Thank you
