Menu Issues

Hi,

I purchased the News Wall Extension as a possible alternative to using a Blog. Itssems to work well apart from a couple of things which I hope you can help with.
When you click on the read more button for a particular item the page opens but with a different layout/colour/font from the main menu on all other pages in the site. The particular page link is www.pottedhistorytours.com/index.php/com...potted-history-tours
How can I ensure that the main menu on this page matches the other pageS?

Also on this page is it possible to have the main image floating to the left so that the body text runs along the right hand side of the image?

Thank you.

Rob
