Add Category Name to REST API

The API responses are designed to only return the IDs. You can then fetch the full information for each term. Of course it would not be very performant to make dozens of requests.

Using a different template per Custom Taxonomies for single term archive pages

Using a loop to display terms associated with a post

This answer was a joint effort with tnorthcutt so I made it community wiki.

Ajax post filter by taxonomy

I believe WordPress can handle multiple query parameter by default. You can load http://wordpresssite.com/?taxonomy-1=term-a&?taxonomy-2=term-b to query all post that belongs to term a (in taxonomy 1) AND term b (in taxonomy 2). Use JQuery load() function to load the intended query parameter, based on the selected item on the sidebar. Hope this help.
