Haneda -Kyoto-Hiroshima-Hakone-tokyo

Hello. We are traveling from Haneda to Kyoto. 3 nights in Kyoto. Then to Hiroshima. 2 nights in Hiroshima, then 1 night miyajima, one more night in Hiroshima, and then to Hakone for 2 nights. Then back to Tokyo for 5 nights, then back to Hakone. I was thinking of buying a 7 day JR pass and activating it for the ride from Kyoto to Hiroshima. It would then be valid to get me to Miyajima, then to Odawara( I know I cannot use it for Hakone). And then form Odawara back to Tokyo. Does this make sense. I was planning on using Nozumi train TO Kyoto, and buying Suica card to get around Tokyo, Kyoto.... Any advice would be much appreciated.
