Dawn, there is a great add-on for Firefox called “Colour Contrast Analyser” from JuicyStudio.

Here is the output of that tool for your site.

Things look good overall, and you need to read the report and say whether or not the combinations listed there can ever occur in the real world or not.

I would also validate the XHTML and CSS at W3C:

Still looks good to me, overall. Nice job.
