Div tags help

Okay…I need some assistance.

I created a header and inside of the header tag i created four additional div tags for the facebook, twitter, etc. All of the icons are positioned on the upper left hand with the float left on the css. However I want to position them on the upper right of the page, position below the margin just a tad, and for each icon separated just a little bit. How do i do that in css? Thanks. Here is link, the code for both html and css. Thanks in advanced.
