I'm categorising my content using taxonomy and displaying the categories in a menu using the taxonomy-menu module.  The way that the menu is being displayed is just what I want, but I'd like to change the way that the linked pages display.

When clicking on a categories menu link, is it possible/feasible to get the page to 

Category name
Category description
Sub categories if any (at this level only, not any further down) with links
Category content if any (at this level only, not any further down) (stories, pages etc)

Is this something I could achieve with Views (which I've looked at but find very confusing)?  

As an example the WebParts link (third level, below HR Portal, within the left hand menu) I'd like:

HR Portal (Term Title)

This is a description of the category (Term Description)

(Term Content - Stories, Pages etc)
HR WebParts - Overview
HR WebParts - Requirements

WebParts Catalogue


Any help would be appreciated, thanks.
