I also recommend you keep Row 2 than Row 1, and flight to ICN try to get Row 1 to 4 when you check in at airport. If you can not get it, stay with upper deck.

Your return flight has Morning Calm Class(sleeper seat)
I think you would be more than satisfy.
Service is very personal, and food is excelent.
you can enjoy Dom Perignon,Dom Ruinart and Krug, and their korean traditional dish(Hanjungsik) is owesome. They willl call you regarding detail menu to be prepared if you leave contact phone # in Korea
First class rounge in ICN is excelent, but one in LAX is lousy since they use Business rounge with blocked wall, and it is small and lots of people

Business class service is quite good though, beaware that seat has less pitch(45') and recline compare than those one in US airlines. there is no power for laptop and Some 744 even do not have PE equipment.
