First time: Planning stage - 2 weeks in Japan

Could you please give me instructions on how I could take use the JR Pass train travelling around Japan for the series of places below - TOKYO / OSAKA / KYOTO / TOKYO

DAY 1 - Arrival via the Narita Airport going to an accommodation in Arakawa-ku Ueno Tokyo ....Narita Express?? Where to stop///which station?

DAY 2 - Staying at the Higashinippori, Arakawa-ku Ueno Tokyo...wanting to go to UENO Park?...

Day 3 - From going to DISNEY LAND or DISNEY Sea...how far from Ueno Tokyo...?

DAY 4 - From Ueno Tokyo...wanting use the Bullet Train...going to Osaka?

Day 5 - Wanting to check out the Osaka Tower, Osaka Aquarium....?

Day 6 - Whole day at Universal Studios

Day 7 - Wanting to wonder around the Osaka parks etc

Day 8 - From Osaka...express train (?) to Kyoto?

Day 9 / 10 - Visiting all the shrines / temples of Kyoto

Day 11 - From Kyoto needs to travel via Bullet train back to Tokyo...?

Day 12 - Check out other place in Tokyo ...

Day 13 - Attend a conference at Big Sights Conference in Tokyo

Day 14 - Check out other places in Tokyo

Day 15 - Travel to back to Narita Airport for a flight to Cairns Australia

Questions...Detailed specifics...?

1. I'm pondering if my 14days JR Pass would suit...I'm actually travelling around 15 days? Also my arrival in Narita is around 9pm..do you think I could catch to change it to a pass when I arrive...?

2. If you're able to give detailed...train/bus/express...on possible major stops for each day...?

3. Do you think...is smart to stay in Tokyo during the Golden Week or travel to Osaka as plan...we are actually arriving on that 29 Apr...until 14 May....? This would be for a family of four = 2 adults and 2 kids (ages 3 & 5)

Any advice would be appreciated...particularly with the day by day usage of the JR Pass...?

Thanks very much.
