You can get rid of two links if you want to, it just involves going into the code.  You’d want to get rid of

<div class="spider2"><div class="ball">{text:Link 3 Short Title}</div><a class="fly" href="{text:Link 3 URL}">{text:Link 3 Title}</a></div>
<div class="spider3"><div class="ball">{text:Link 4 Short Title}</div><a class="fly" href="{text:Link 4 URL}">{text:Link 4 Title}</a></div>

Be careful not to delete any more code than that.  It will seriously screw the theme up if you do.

As for the About page, if you’re using a customized About theme, when you make the page you have to set the layout to “custom layout”.  See tutorial here.

Hope this helps!
