Suica & N'EX from Narita

I plan to purchase a one way Suica & N'EX for 3500 yen traveling from Narita to Tokyo Station. Does my N’EX cover travel onward to another JR Station? I need to get to Hamamatsucho Station. If not assume I can use some of my Suica card to travel from Tokyo Station to Hamamatsucho Station. Thanks…I can’t seem to find a straight answer on the web.

As long as you don't exit the turnstiles, you can use the transition area of the station to get to Hamamatsucho on your N'Ex. I can only remember how to do it at Shinagawa, but doing it there may be easier than Tokyo Station.

If enough time regular JR Rapid(suica only) cheaper than NEX.
NEX is comfortable but not very fast like Shinkansen.

As shown here http://www.jreast.co.jp/e/suica-nex/index.html N'EX ticket is valid within the colored area as long as you don't exit ticket gates.
When you buy your S&N'EX package tell the ticket office clerk your destination than just ride the N'EX and change at Tokyo or Shinagawa Station to Yamanote line using only your JR Ticket
