How to activate Fuji-Shizuoka pass and use it to take buses?

Hello. I have already bought a Fuji-Shizuoka pass. My plan is to go to Shimizu Port first and then take the ferry to Toi port and then take buses from Toi Port to Shuzenji. The next day I will take bus from Fujinomiya to Lake Kawaguchi and then go to Gotemba. I want to ask some questions.

1. Can I activate my ticket at Toyohashi station?
2. Can I take the ferry from Shimizu to Toi Port, using the pass?
3. If I want to take bus from Toi to Shuzenji, what bus should I take? I found 2 lines from Google, Tokai bus Line W30 and Line W39. Are they included in the pass?
4. If I want to take bus from Gotemba station to Lake Kawaguchi, what buses should I take? I found A-Line C-Line from Fujikyu bus. Are all bus lines of Fujikyu available for me to take?

Thank you very much.
