CWDO CSS cleanup and mod

[login to view URL]'s (a non-profit) site has been moved from static pages to drupal. The template has been converted into a basic drupal theme with a quick merge with Garlin. The original site was poorly coded, the HTML & CSS is sloppy but they'd like to retain the look. Project Goal: 1) To clean up the CSS and format the page look to better conform to the old look. 2) ensure that the CSS renders the same on IE 6-8, Safari, Chrome & Firefox. 3) combine styles and better organise the CSS 4) ensure that the site works with both a 2column and 3 column layout 5) ensure that it renders fine when CSS is turned off
