Ok, after much

I found a partial fix for my issue. Also, just for the record, I did start with a fresh stylesheet and followed the instructions for setting the width of my side boxes. Even after doing this IE still condensed the box heading down to the size of the text.
To correct this, in my Stylesheet on line 686 (may vary depending on your edits) look for {h3.leftBoxHeading, h3.rightBoxHeading}. I then entered values for the left and right padding. {padding:.2em 5.2em 0 5.2em;} This gave me a more desirable result in IE and FF lines up just perfect. You may need to play with the numbers to get things just right. Check out my results by clicking on Monumental Photos in my signature. Hope this helps someone down the road.
