Custom Post Type Taxonomy Filters

I would take a look at this page on the Codex: http://codex.wordpress.org/Class_Reference/WP_Query I think you need to override your query_posts() for your landing page, and controlling different queries with if() statements, depending on what areas of a form (guessing you’re using a form?) has filled in.

Get posts by term slug only

If you look at source of get_term() it does hard check for taxonomy and for good reasons (caching, collisions, etc). I see two possible approaches: look for term in every appropriate taxonomy until you match try to query for term by search or name__like in multiple taxonomies using get_terms() and work with results

How do I taxonomy terms based on terms they are used alongside?

So my solution on this kind of problems where we have a very complex set of rules is to avoid doing new SQL just for my solution because if you have to explain it to a beginner it gets hairy.

Like Justin Tadlock says in your referenced article, the body_class() provides the ability to add classes dependant on the type of term. Given that you indicate your php knowledge is still growing; this maybe the best solution. The codex provides a list of classes on a body_class enabled: http://codex.wordpress.org/Function_Reference/body_class If that isn’t sufficient; wordpress has …

$wpdb: Counting posts corresponding to 3 terms in 3 different taxonomies

Do a tax-query and then count the result. No need for a custom query with dozens of JOINS. $posts = new WP_Query( array( ‘post_type’ => ‘MYPOSTTYPE’, ‘tax_query’ => array( array( ‘taxonomy’ => ‘TAX_1’, ‘field’ => ‘slug’, ‘terms’ => array( ‘TERM_TAX_1’ ), ‘operator’ => ‘IN’ ), array( // etc. ) ), ‘post_status’ => ‘publish’ ); prinft( …
