Did some searching. Got a code to work, I pasted it below the template it came with, new code in bold.
Theme Name: Themeology 1.3.1
Description: Semantic, SEO Optimised, Custom WordPress Theme for Themeology
Author: Brandon R Jones
Author URI: http://www.makedesignnotwar.com
/* Themeology */
/* CORE STYLESHEET */
/* Stylesheet IMPORT Themeology */
padding: 0 50px;
border: 4px solid #f0f0f1;
background-color: #909090 url("path/to/blockquote.gif") no-repeat 0 0;
Not sure how to get a background color and would also like to narrow the box so it's not so wide. Going for something like this still.
