Can you please help me decide which JrPass is suitable for my itinerary

Hi,

I can't decide which is better for my itinerary 7 Day pass, 14 Day pass or some regional passes combined.
So here it is my itinerary:

23April arrive at Narita, then I will go to Kanazawa
24 - Kanazawa
25 - From Kanazawa to Kyoto
26 - Kyoto
27 - Kyoto
28 - Kyoto
During the days in Kyoto I want to to go during one day to
Hiroshima and Miyajima
29 - Kyoto to Osaka
30- Osaka
1 May - From Osaka to Yamanakako Mt. Fuji
Is the bus from Mishima to Yamanakako bus station included in JrPass?
2- Yamanakako
3- from yamanakako to Tokyo
4- Tokyo
5- Tokyo

So, I have done a lot of research in sites like hyperdia. But i can't decide which one is more suitable or if is possible to combine some regional passes.
And if any buses are included in my trip.

Thanks in advance.
