7 day JR Pass

HI, I will be going to Japan on the following itinerary.

Nov 2 Arrive Narita airport and wish to start the 7 day JR pass to Kyoto.
Nov 3 - 5 Koyto
Nov 6 Leave Kyoto to Osaka using JP pass
Nov 7 Osaka
Nov 8 Leave Osaka to Tokyo using JR pass
Nov 9 Day Trip to Hakone
Nov 10-11 Tokyo
Nov 12 Narita Airport, departing Japan

1) Should I buy the 7 day JP pass and is the last day of usage on Nov 8 Midnight ?
2) For the day trip to Hakone, if I buy the Hakone Free Pass, am I able to use it on Odakyu Romancecar?
3) Can the JR pass use for day trip to Uji and Arashiyama from Kyoto?

Thank you very much.
