Need help correcting column widths

I went in a tinkered with my column width to give me more space for writing and pictures in the main sections and now the side menu is under all the posts. No matter how I tinker I can't fix it. I am used to blogger and this is not performing like that interface. Can anyone help?
thnx!! Michelle
