Also, is there a way that I can keep the logo stationary at the top of the page?
You can do that with fixed positioning. Here is some additional background information about it if you are interested:

The Oulipo theme actually does use fixed positioning already, but you overwrote that when you added the following custom CSS:
#main-nav {
background:url('http://bunandbiscuit.files.wordpress.com/2012/05/girlwdog_145x218_logo.jpg') no-repeat scroll 0 0 transparent;
margin:0;
padding-top:9em;
overflow:hidden;
position:absolute;
}
#main-nav h1,#main-nav .description {
margin-left:-500px;
}
Are you interested in switching back to the original way Oulipo makes the left title and navigation a fixed position so it doesn't move when it's scrolled?
