How to show the list of taxonomies in specific category

I've been tryign to figure this out for some time, and it's now startign to get a bit scary as I need to get this site done before Saturday (I have a conference).

All I want to do, is show a list of posts in a specific category of a taxonomy, just as if it were a catgory page.

From reading around, this should be possible by typing in:

http://www.domainname/taxonomy-name/category-name

I can't seem to get this to work though, even when using the default theme.

In the instructions, near the end, it says:

Use the auto generated taxonomy and custom field embed code to place it inside your WordPress loop to display them within your theme

This is the embed code I have:
<?php echo get_the_term_list( $post->ID, 'link', 'Before: ', ', ', 'After' ); ?>

Where in the loop and in which file?

Thanks.
