Rich,
the F seats have a 'guest' seat, across from the main seat. This way you can sit facing eachother for talking or eating. Given this it does not really matter where the 2 of you sit, though 4/5 E&F are indeed good if you want to be able to talk to eachother while sitting in your own seat or watching a movie.
