4/12 through 4/21, 2012, JR rail pass check

Hello, thank you for your time and effort. Itinerary is:

4/12, Arrive Narita, purchase 'Narita Express and Tokyo Metro combined travel package' if still available, night in Tokyo
4/13, Night at Tokyo
4/14, Activate JAL rail pass, train to Hiroshima, night at Hiroshima
4/15, Night at Hiroshima
4/16, Train to Masuda City, night at Masuda City
4/17, Night at Masuda City
4/18, Night at Masuda City
4/19, Train to Kyoto, night at Kyoto
4/20, Train to Tokyo, night at Tokyo
4/21, Flight out

The two questions I have are: is the 'Narita express and tokyo metro combined travel package' still available for purchase and on 4/21, will the JR rail pass still be active or would the train fares on this day, be out of pocket? Thanks in advance, looking forward to this trip!
