Getting Tickets With JR East Pass

Thank you for your extensive answers when asked questions by other members, you have no idea how incredibly helpful it is. With that said I have a couple questions for a first timer.

1. In order to get a ticket in a station, do I need to show my pass each time at the manned window and they will issue me a ticket for that particular train? Does this include not only the Bullet trains but short local trains?
2. Will they choose the right JR train for me so that I'm not guessing which line is valid with my pass?
3. As stated above, I've bought JR Pass EAST - unfortunately I did not look at the map correctly and Osaka and Kyoto is outside my Passes travel range, will I need to purchase ANOTHER Pass for that region?
4. Do you have a National Pass that encompasses the entire Island?
5. Is it more advantageous to get a Suica card for all my in town travels like Tokyo, Osaka, Kyoto etc?
6. I've been told there are some stations that are unmanned. Are JR Lines Clearly marked in order for me to get the right train? How do you redeem your Pass in a situation like that ?

Thank you in advance I, again along with others I'm sure, deeply thank you for all your detailed answers!!
