Hi AusA380, all seats in row 1 are bulkhead, with regards to easy access, I assume you mean when the seats are in bed mode?
You'll have to climb over your neighbour no matter which A/F/K seat you sit in as the bed extends pretty much all the way to the wall.
As for noise from the bar, it's usually pretty minimal, only 6 people are allowed to occupy the area at one time. And there probably wouldn't be much noise from PE either.
Wherever you sit you'll love it, VA J on the 77W is a fabulous way to fly.
