Creating basis for Google analytics reports on a wordpre

My site is avelim.co.il. The site is on Hebrew wordpress 3.3.1, using the theme Weaver 2.2.6 with many customization done by programmers. I am using the plugin Google Analytics for WordPress by Joost de Valk The site has 442 post categories. Some posts belong to several categories. The number of categories will increase. I need to be able to produce the following analytics report for each category: Traffic data for the posts of the category for a selected time frame. This should rate the posts in the category, and produce the total for posts in a certain category. This should work for future categories too. The work will be done on a test site, and when successful done on a live site. The proposing freelancer should describe how he intends to get the desired result: Installing another plugin, inserting a code, changing things in the Google analytics settings etc. The project will be considered complete after 14 days that the freelancer finished is part. This is to allow for bug finding and testing.
