This is the second time you have posted this question. The first time I looked at your site. I think it's far more complicated then it needs to be. I could not follow anything.
Here is a general explanation to do what you want:
You have to use AJAX. Your tabs call the ajax function and pass it an identifier. Ajax then calls a server-side script like PHP. That script gets the identifier and obtains the info and passes it back.
A second method:
Problem with this method is you have to change the HTML of your index page each time there is a change in what you want displayed. You can ruin the index page if your not careful!!!
One last thing IMHO you should light the tab that is displayed.
