Unfortunately it looks like another potential easter egg has been shot down - after doing a simple IMDB and then Google search on the actress in question I found this picture, showing the tats are from the Matthew Fox school of thought. However, that's not to say that they might not be added to the narrative (as per Jack), but definitely not a blatant easter egg as such I'm afraid. Notice though that rather than "a lame protein molecule" (what a lovely description), the tat is in fact four squares connected by a line, with letters on each one. Looks like RM something something, but then again I don't really wanna pry and find out what it means - that's her business not mine (unless they use the letters to make the name of a flashback character on Lost, etc).
No further news yet on the Korean writing on the Paik logo, though as its written instead of verbal, I might have a better shot googling it later. I'll post my findings if they are interesting.
