Hi Lisa
I'm on IE7 and still getting the 'popping out' on the right side of the site - like your main site frame is too small for the sidebar? Try increasing the container size...
On your About Us page I might suggest moving some content up to the top (above the images) so your visitor doesn't have to scroll down to start reading. Breaking it up in the middle with images (so they're still partially visible above the fold) will allow you to maintain the color, etc. on the page at first glance but will also make it easier for your reader to get the info they want.
I really like the look of your site overall - so far so good!

And great logo!
