Browser Compatibility Problem

Display Wizard

New Member

Fairly new to web design and just working on my first site but have a few issues with browser compatibility. The site works fine on Safari, Firefox, Opera, IE8 but when its comes to IE6 and IE7, I run into a few problems.
Have a look at the site here:

Exhibition Wizard

The first bug is the alignment of the Home link and small picture.

The second is all text is being shown as a link and formatted as a link.

Does anyone know what these bugs are and what to do to fix them?
