plugins and adding top navigation.

I would like to add top nav for categories above the header. http://www.pollenater.com (EDU Homepage theme)

Is there a widget that allows each individual user to post to all their social network sites like the "social floating widget?" So when a user signs in and finds something interesting they can post it to their other networks with a click. Right now the social floating widget posts to our sites social medial no matter who's user account is signed in.
