Output section and tag name with URL in entry loop
Sections do not have URLs, so section.getUrl will not return anything for you. 

If you are trying to get an index page of all the entries in a section that has a URI, try slicing off the last segment of the entry's URL, and make sure you have an index.html template in that section's template folder. Take a look at the templating documentation for more information on this. 

For the tags, make sure you call  {% for tag in craft.tags.relatedTo(entry) %} instead of {% for tag in craft.tags.relatedTo(entries) %} to get the tags related to the entry you are currently focused on in the for loop.

Hope this helps!
