The two pages for the home typically happens because the WordPress default for creating new pages adds them to your menu structure automatically so that new users aren’t creating pages that are “orphaned” or which can’t be navigated to from elsewhere within a site. It’s likely that you created the About me page and then changed from your stream/blog on your front page to using a static front page with that same About me. Not knowing that it’s already in the menu structure, WordPress just changes the home link to the new static page thereby duplicating it. I think I’ve done something like that about a dozen times. I suppose it’s better having it there twice than not having it at all…
