Problems at higher font settings in the browser

[liunx]

Greetings,

Welcome to another episode of "Why is my page broken!?!?!?!"

I'm building a site for my friend who owns a small t-shirt business. I vowed that (for the first time ever) tables would not be used for the layout. Everything was going fine until I enlarged the font in my browser. I would really like the site to be as accessible as possible, and thats why I've posted.

Here's the style sheet:

<!-- m --><a class="postlink" href="http://www.destructiveclothing.com/00style.css">http://www.destructiveclothing.com/00style.css</a><!-- m -->

This page gets really funky somewhere around 26pt.

<!-- m --><a class="postlink" href="http://www.destructiveclothing.com/designs/human.php">http://www.destructiveclothing.com/designs/human.php</a><!-- m -->

The tables on this page extend to the right even at lower font sizes(I don't consider this to much of a problem, although is a little wacky).

<!-- m --><a class="postlink" href="http://www.destructiveclothing.com/custom_printing.php">http://www.destructiveclothing.com/custom_printing.php</a><!-- m -->

I was wondering if anyone knows a better way to format the first example, and possibly if there's a fix to the table issue in the second example.

Thanks in advance.
