Tokyo>Hakone>Kyoto>Osaka - 7 days pass?

Hi All

Would appricate some advice as to whether to buy the 7 days pass. Here's our itinerary:

4th Nov land in Tokyo
8th Nov travel to Hakone
9th Nov travel to Kyoto
12th Nov travel to Osaka to the airport to fly back.

If i do purchase the 7 days pass, would it be worth also puchasing the Hakone Free Pass on top of this or use the pass to go to Odawara?

Would anyone know if i can use the pass to get from Kyoto to Osaka Aiport (Kansai)?

Thnak you in advance.
