Hi JS,
Flying east from the east coast the upstairs in UC is designated the "Snooze/Sleep Zone" so there is no meal service in your seat, you need to go to the bar to eat, it's lights out shortly after take-off and they will wake you up an hour or so before landing for breakfast.
You should have the suite but it could always be J2000 due to a plane going tech or delays, etc. There is no down side to either seat if you are happy with the "Snooze Zone" arrangement, if not get a seat on the main deck.
And yes, you are right, you cannot pre-book bulkhead (or exit) rows.
