Style Sheet Problems

In layman's terms how can I do the following:

Below is a copy of my current style sheet, to which I am having problems.

But, first, here's what I am trying to accomplish: 3-Column Static width and Centered Layout.
Therefore, I want the entire background to be #C0000 (rgb 192,0,0); I want the content header, the contenT left & right headers (columns) to be #009999 (rgb 0,153,153); the content center column to be #EEEEEE.

As for the font color I want white in the header, left and rigt column; and, black in the center column. Moreover, I would like the sub-headings in #C00000 (rgb 192,0,0 ).

CURRENT STYLE SHEET, for willametteweb.us:

body,td {
text-align:center;
}

#frame {
width:840px;
margin-right:10px;
margin-left:10px;
margin-top:10px;
padding:0px;
text-align:left;
}

#contentleft {
width:175px;
padding:0px;
float:left;
background:#009999;
}

#contentcenter {
width:510px;
padding:0px;
float:left;
background:#ffffff;
}

#contentright {
width:155px;
padding:0px;
float:left;
background:#009999;
}

#contentheader {
background:#009999
}

p,h1,pre {
margin:0px 10px 10px 10px;
}

h1 {
font-size:24px;
padding-top:10px;
}
