Joomla Template troubleshooting

I have a Joomla website which needs some template work on a Joomla website: There are two items that require work: 1. A working right hand column which is needed for the 'Latest News' module. The right hand column needs to have a border separating it from the main content on the left hand side. It needs to display up to 5 latest new items and format nicely in Firefox and IE6 and IE7. 2. I need to have the banner module working on this template. At the moment there is no place for the banners to display if they are published. I would like a div created for banners (using the Joomla Banner Manager) that will enable a banner to be displayed below the main content (above the footer) or above the main content (below the top menu). There is a development version of the website to make these changes - so you don't have to worry about working on the live site.
