Enjoy ICN - I've always enjoyed that route in F. I love the smaller F cabin, especially 4F and 2K, plus the escort through security at ICN whe travelling F.
Yes, it's still the Asiana lounge with the special toilets
Re the CCR, I've been able to eat from the lunch menu at 11.30 before - in the days when I had a CCR card and new some of the staff there - a polite request should achieve what you're looking for
Enjoy..
