Modify Wordpress blog function

I have a Wordpress blog that uses jQuery and CMS--it's called Quiktab [login to view URL] For each post, you need to add tag "panel" and then it displays a new item in the left menu titled post headline and places post body in the main area. 1) I need to be able to make posts that will by default display headline and body in main area--under the "Home" left menu item. I do not want to create a new menu item for every post. 2) Previous posts need to be placed in "Archives" menu item as new posts are added. 3) Users need to be able to comment on posts. As is there is no way for them to ## Deliverables 3 deliverables--all installed on the blog in working form: 1) All new posts appear headline and body in the main window when Home menu tab is selected 2) Previous posts move to headline and body in the main window when "Archives" menu item is selected. 3) Users need to be able to comment on posts.
