Front Page & First Taxo Pages Break Float

I'm having a bit of trouble customizing this theme. I have it set up as a 2-column blog with the right side bar. However, when I look at the front page, or the first page of a taxonomy term list, the right sidebar doesn't float to the right...it's falling below the main content area. BUT, if I click on the pager to go to page 2, 3, or any other pages in the list, everything works fine. Any thoughts?

here/s what part of my css looks like now (i didn't edit anything not shown):

*{
	margin:0;
