Custom category page

I’m looking to create a custom category page for one of my categories.

I’ve got the HTML and PHP all set up and it looks good, but, I’m wanting to do something that I haven’t seen done before. Not to say it hasn’t been done, I just haven’t seen it.

The category page in question is called Interviews. It won’t have any posts — it’ll just have subcats of the people I’ve interviewed. And those subcats will have posts.

For example, if I’ve interviewed Bob Dylan, Madonna, and Dave Matthews, the category listing would look like this:

Interviews
–Bob Dylan
—-Bob Dylan Interview post 1
—-Bob Dylan Interview post 2
—-Bob Dylan Interview post 3
–Madonna
—-Madonna Interview post 1
—-Madonna Interview post 2
—-Madonna Interview post 3
—-Madonna Interview post 4
–Dave Matthews
—-Dave Matthews Interview post 1
—-Dave Matthews Interview post 2

I want to do two things on the “Interview” category page.

1) Display all the subcategories automagically. I am currently doing this with ‘wp_list_categories’, but it doesn’t do 2 and 3 below — and seems to prohibit 2 and 3 from happening. The title would then link to the subcategory page, which would look like all the other category pages on the site.

2) Display an image associated for each subcategory. I know that’s not
default in WP. Any good plugin recommendations for associating an image with a category?

3) Display the description for each category.

Any thoughts on how to do this would be greatly appreciated.
