Regarding West JR Sanyo-Sani'in

Good day,

I have 2 questions regarding sanyo-sani'in pass
1. Is it possible for me to redeem the e-MCO of the pass on Hiroshima Station exchange place instead of KIX airport?
2. Do west jr pass only cover routes from/to station viewed on the detailed map? Or do they also cover route from/to the station in between? In general, what kind of train/transportation means they'll cover?

My wife and I will travel to hiroshima-osaka-kyoto next month and this will be our very first visit to japan. So I need your help and guidance. Thank you all...
