JR Pass for 13 days itinerary - seek help

Hi,

Below is my draft trip to japan on xmas day December 2016. We plan to travel frm Tokyo - Osaka - Hokkaido - Tokyo. I am planning to purchase JR 14 days pass. But i am not sure which shinkansen bullet train that i can follow. I am confuse.

Day 1 = arrived narita airport - via JR or Narita Express to tokyo /Shinagawa station? Then to Shin-Osaka via Tokaido Sanyo Shinkansen). I am sure which bullet train to follow, cos JR Pass can not follow NOZOMI right?

Day 2 - Day 5= kyoto, nara, usj,nagoya (via JR Line)

Day 6 = from shin-osaka - via JR Shinkansen to Hakodate (i still need to stop at Tokyo to change shinkansen right)
(can i do a reservation on JR Seat? Can i do this when get my JR Pass on Day 1 at Narita Airport? (Which shinkansen bullet train i should take)

Day 7 - Day 10 = JR hakuto around hokkaido area. Can i use the JR pass for otaru bus?

Day 11 = JR Hakuto to Hakodate, then take Tohuko Shinkansen to Akihabara station (Which bullet train to follow?)

Really seek your help for this. Thank you very much
