Wordpress Theme (Amendment)

Hi. I have purchased a Wordpress theme: [login to view URL] I would like the following additions: In Wordpress CMS you can add a category description for each category... however, this theme does not show this text! I would like it so that if I add a category description, it would be shown on each category page, for example: The 'Attractions' category page: [login to view URL] The description would be shown in between the 'Home » Attractions' breadcrumb and the 'sort by' tab. - It would only show the first 200 characters, I would then like it to show a 'read more' tab, that, if clicked, would then show the rest of the description, like this example 'read more': [login to view URL] (also to have 'close' button to then show just the first 200 characters again. - I will send you all the current PHP Wordpress theme files and I will expect all items back (that have been changed) to be ready to use.
