NO you can only go as far as the current date they are accepting reservations.

b. if not, can one resched. Oct 2016 reservation to later date free? Or cost?

You can reschedule but there is a change fee if the change is made less than 8 days before the flight.

c. $15 redemption fee is regardless of travel date vs. reserving date?

The is no fee if reserving 180 days out, there is a higher fee if reserving less than 20 days out.

Thanks!
