Here, I've done 90% of the work for you:
body
{color: black !important;}
a:visited
{color: #030 !important;}
div#masthead, div.content_nav, div.user_panel
{display: none !important;}
#mpu_col_wrap
{margin: 0 !important;
padding: 0 !important;}
.col_layout
{padding: 0 5px 0 5px !important;}
textarea
{width: 100% !important;}

CSS's "!important" is uncannily like INTERCAL's "PLEASE", isn't it? You'd think it would go without saying that when you're talking to a computer, you want it do what you're telling it to do.
