Elements not displaying correctly in IE7

Hi

I wondered if anybody IE-bugfix-savvy person could help me please.

I am trying to “reverse-engineer” my CSS as it is not displaying correctly in IE7. On the home page of my site the Twitternews title background is being pushed down so the title appears misaligned. I am tearing my hair out! Also the first element in my left sidebar menus on other pages are also showing a similar mismatch bug… Is this a :first-child issue or something else?

Thanks to anyone in advance who might be able to set me free!
