[SOLVED] Styling Body Links

Hi. Great theme, we've been using it for a while now and really like its usability.

I'm having an issue with a bit of styling I added to 'Add HTML/CSS inserts'

.post-bodycopy a:hover {
background-color: #000000;
}

it's working fine but it's adding a background to the ADDTHIS social buttons at the top. I can see that they are included in the body div but not sure how I can separate them?

Here's a post as an example

On a different subject I wondered if there is a way of adding a footer with content/widgets?
