How do you make the starting boxes on facebook go away?

I made a new facebook account, and I already know how to use it and everything, but I'm constantly being annoyed by all the introductory boxes popping up. One is a find friends box by the top where you click to go the the home page, your profile, and account. Another is a box like an ad on the top right that tells me what everything is when I run my mouse over something. Is there anyway to get rid of them? Or will they just disappear automatically later. Please help!
