Creating new sections based on "article"

I found an old question http://groups.drupal.org/node/46444 about duplicating the "article" content type, its listing page, and node detail page for use as new content sections. (obituaries, sports...)

As I understand things, I need to:
- Duplicate the "article" content type;
- Duplicate the "article" view;
- Duplicate the "article" context

This will let me, for example, create an "obituary" section with its own listing page, individual nodes ("article pages") for the individual listings, and a block for the front page with a few of the most-recent listings. Same idea repeated for a few other sections.

I've been chipping away at this for a few days, and keep hitting various snags... I'm almost able to get there, but can't quite make it work. Does a "how to" for this process exist somewhere that I've missed, or would someone who has done it be willing to walk me through it?

Thanks for any guidance.
