I think it is the amount of padding on the content area? In IE it breaks down. Any help would greatly be appreciated!

sorry for my english but..

do it in that way:

left column must be sidebar1
center -> content
right column -> sidebarr

all will work that way

<div class=“sidebar1”>...<>
<div class=“content”>...<>
<div class=“sidebarr”>...<>
<div class=“clear”><!——></div>

with style

.sidebar1,
content,
sidebarr {
  float:left;
}

.clear {
  clear:both;
  height:0px;
}

make all with fixed width and fixed margin in one fixed width container(div) with margin:0 auto; (to make them centered)
repair all for IE (i mean double margin with float elements) (in example if you have margin-right:4px then must have * html ELEMENT { margin-right:2px; } this is bug: “double margin in float elements”

this must work :)
