Tottori bus pass

Hi.
I am planning to go to Tottori around March next year from Osaka by bus.
There will be 4 of us.
I want to ask about this bus pass: Tottori-han noriai bus norihodai tegata.
I understand that this bus pass allow me to use most buses in Tottori prefecture for three days at 1800 yen.
1. I want to know whether this bus pass allow me to use the bus for these route:
a) Tottori station to Kurayoshi station
b) Kurayoshi to Yonago station
c) Yonago station to Tottori

If yes, where can I check the bus schedule?

2. If no, do I need to buy the San'in-Okayama Area Pass for the trip? Since this pass is 4500 yen, should we just rent a car and self drive instead? Is there a more economic way?

My trip would be 2 full day, by arriving in Tottori one day before around late evening. I am interested to visit the sand dunes, misasa hot spring, kurayoshi white wall warehouse and mount daisen. If time permits, would like to include Uradome too.

Please advise. Thank you.
