I need an opening

I usually start with the classic e4, Kf3, then Bb5 to allow for a quick castle. After that though, I really don't know what to do, and my game results reflect that. 

I know that part of it is my horrendous middle game, but I know that most of that will come with more play time. I feel that my first four or five moves just aren't doing it for right now.

I suppose it's back to the books.
