JR pass or regional pass?

Hi JR Pass Team,

My husband and I are travelling to Japan for two weeks in March and our Itinerary is as below:

17th March - Arrive at Narita and go directly to Kyoto.
18th - 21st March - Kyoto + Nara
22nd March - travel from Kyoto to Osaka. visit Himeji.
23rd March - One day trip to hiroshima and Miyajima
24th March - Travel from Osaka to Kanazawa
25th March - One day trip to Takayama
26th March - One day trip to Shirakawa-go
27th March - Travel from Kanazawa to Tokyo
29th March - One day trip to Hakone
30th March - depart from Haneda.

Could you please suggest if I should get a 14 day pass or a 7 day pass + regional pass (if so which regional pass will be best?) Can I use the JR pass to travel within a city for example - use the local busses and trains?

Thanks a lot in advance for your help.

Regards,
Shruthi
