VERIFICATION ON APPROPRIATE JR PASS

I will arrive in Osaka on a Saturday, going to Kobe to be with friends till Monday. I will purchase a 1-day Kansai Pass to get to Kobe. Or is there a ferry from Osaka to Kobe?

Monday I will leave to go to Kyoto till Friday. I was planning on purchasing a 4-day Kansai Pass and a 1-day Kasai to cover my 5-day stay and to return to Kobe.

Friday I will be in Kobe to be with friends till Monday. No pass needed.

Monday I will go to Hiroshima returning to Osaka on Tuesday for the remaning stay. I will purchase a 4-day West Pass.

My question, is this my best option or is there something better and more cost efficient?

Any suggestions are greatly appreciated.
