Custom post type category permalinks and archive pages

Question

I know this question was brought up before, but I can't seem to get things working using any of the proposed solutions. This is how I have my custom post types and categories setup:

Custom Post Type: Buildings
-Buildings Categories:
--Medical
--Industrial
--Educational
--Recreational

-Buildings Regions (custom taxonomy):
--USA
---Connecticut
---New Jersey
---New York
--Canada
---Quebec
---Ontario

Every Building will be assigned to 1 building category (Medical, Industrial, etc) and 1 building region (USA->New York, Canada->Ontario, etc). This all works fine, except the permalinks to inner building pages are site.com/buildings/postname and there is no category archive for the custom post type categories. Here is what I'm trying to achieve:

1. Permalinks to inner building pages to be example.com/buildings/category/postname

2. Permalink to archive of all building pages to be example.com/buildings

3. Permalinks to archives of each building category example.com/buildings/category

4. Lastly I want to be able to display an archive of buildings by region. So example.com/buildings/region/usa would bring up all the buildings in the USA, while example.com/buildings/region/canada/quebec would bring up only buildings in Quebec, Canada.

I've tried numerous solutions, but the closest I was able to get was half of #1 working using the WP Permastructure plugin posted as an answer to this similar thread. I am able to get the permalinks for inner building pages to generate properly, but when accessed they return 404s.

Any help is greatly appreciated!

Yev, without a code sample to work from I'm not sure how helpful I can be but I'll give you the code that I use for creating Custom Post Types with a archive page. This example will get you started for an FAQ (easily modified).

Note the rewrite lines and the flush, which is what creates a permalink structure for the Custom Post Types (and flushes the cache to activate it). I suspect this will get you fairly close to what you're hoping for but if not, submit your code and I'll try to help.

if ( ! function_exists( 'new_cpt_faq' ) ) {
    function new_cpt_faq() {
        register_post_type( 'new_cpt_faq',
