At first, Kirito was going to take Klein with him, but he decided for not because Klein already had friends, and he didn't wanted tot keep more than one person with him.

If Suguha had entered SAO she would probably had met Kirito because the were using their real world appereances, but with that, a lot of things would have changed, like his help to Silica or the Black Cats of the Full Moon Incident

It could be a good topic for fanfic.
