Help With Theme Width Please

[Spice]

Will this help?
The following is the portion of the CSS for the theme I am working on. As far as I can see there are only two areas where you adjust the themes width. Am I wrong?
body {
background: #ffffff url(http://i1165.photobucket.com/albums/q583...3b8fd0.png);
color: #333;
text-align: center;
line-height: 1.4;
margin: 0;
font-family: Tahoma, Verdana, Arial, Sans-Serif;
font-size: 14px;
font-weight: bold;
overflow-y: scroll;
}

a:link {
color:#4e2a16;
text-decoration: none;
}

a:visited {
color: #4e2a16;
text-decoration: none;
}

a:hover,
a:active {
color: #9d6d2f;
text-decoration: underline;
}

#container {
background: url(http://i1165.photobucket.com/albums/q583...c1630b.png) repeat center top;
background-position: top center;
background-attachment: fixed;
border: 15px double #bb7755;
margin: auto auto;
margin-top: 50px;
margin-bottom: 50px;
border: 15px double #bb7755;
text-align:center;

width:75%;
}

.wrapper {

width: 75%;
min-width: 970px;
max-width: 1500px;
margin: auto auto;
}
