Hello,
about the category pages. You may get closer to what you want to achieve if you add the category as a drop down in the search bar.
In the next version of GD the category will be automatically selected when the search bar shows on a category page. That won’t apply to tags, though.
For the directions, there are two options.
In GDV2 we have made a new element that you can add to the Archive or Details page template that creates a link to get directions from the user’s map program: gd_post_directions

It is also possible to display the directions UI for a post map. You will need to create the shortcode yourself for the GD Map and place it inside the GD Details template. For example:
[gd_map width="100%" height="425px" maptype="ROADMAP" zoom="0" map_type="post" post_settings="1" map_directions="1"]
