I do I add just a home page tab to my menu bar??

I got my color right on the page, but I think my right sidebar information is still on my page. Even though I have nothing in it. This is what is listed in the style page under sidebar:

#sidebars ul{
padding:0px;
margin:0px;
list-style:none;
padding:10px;

}

#sidebars ul li ul{
margin:0px;
padding:0px;
border-bottom:0px solid #ebc0d5;

}

#sidebars ul li ul ul{
border:none;

}

#sidebars ul li h2 {
color:#fff;
padding:0px;
margin:0px;
padding:5px 10px 0px 22px;
font-size:1.4em;
background-image: url(images/h2bg.jpg);
background-repeat: no-repeat;
height:37px;

}
#sidebars ul li ul li{

border-bottom:0px solid #f5f5f5;
padding:5px;
color:#000;padding-left:20px;

}

#sidebars ul li ul li li{

border-bottom:0px solid #f5f5f5;
padding:5px;

}
#sidebars ul li ul li li a{
color:#222;

}

#sidebars ul li ul ul{
margin:0px;
padding:0px;
border-top:0px solid #eee;
}

#sidebars ul li ul li a,
#sidebars ul li ul li a:visited
{
color:#730000;
text-align:left;
font-size:1.10em;

}
#sidebars ul li ul li a:hover{

}

#sidebars ul li ul {
margin-bottom:10px;

}

I was able to remove my right sidebar, but now I have this huge white space. I looked in the style css, but there is no width to change in the content area. So how do I adjust my width to go across the rest of my page to the right?
