I think what you are looking for is this: http://codex.wordpress.org/Function_Reference/get_terms

Example of how to get all my_taxonomy terms and echo them in an unordered list.

 $terms = get_terms( "my_taxonomy" );
 $count = count( $terms );
 if ( $count > 0 ){
     echo "<ul>";
     foreach ( $terms as $term ) {
       echo "<li>$term->name</li>";
     }
     echo "</ul>";
 }
