Most cost effective option?

Looking for some advice on the most cost effective way of getting around for the following itenerary. We were thinking about a 14 day JR pass and starting this when we leave Tokyo for Kyoto but not sure if this is the best way round as we would then have to pay for travel from the airport into Tokyo and for trips made in Tokyo.

1. Narita airport - Tokyo
2. Tokyo
3. Tokyo
4. Tokyo - Kyoto
5. Kyoto
6. Kyoto - Osaka - Kyoto
7. Kyoto - Hiroshima
8. Hiroshima - Kanazawa
9. Kanazawa
10. Kanazawa - Hakuba
11. Hakuba
12. Hakuba
13. Hakuba
14. Hakuba
15. Hakuba - Haneba airport for midnight flight

Suggestions would be very welcome. Thanks.
