Sure Kim : )

It turns out that I didnt have all my center widths the same throughout the CSS...SOOO once I changed this on the stylesheet_original...

.centershop {
padding: 0px;
margin: 0px auto;
/*position: relative;*/
text-align: left;
width: 800px !important;
}


and this on the stylesheet_new...

#mainWrapper {
background-color: #ffffff;
text-align: left;
width: 800px;
vertical-align: top;
}

So that they both matched at 800px...everything lined up as planned in both Firefox and IE.

YAY!
