I have done considerable reading on both Node.js and Backbone.js; I\'ve read some tutorials and done the relevant courses on Code School. I feel that I\'ve got a pretty good ide
This is a good tutorial that shows how to setup that entire stack.

In short...
You can use a library like restify to provide a restful API for your client-side Backbone application. It can also serve your static assets for your Backbone application. The example uses restify, but could be accomplished with other libraries like express.
Mongoose is a javascript abstraction layer for MongoDB. This provides an easy way to interact with MongoDB from Node.js.
Your Backbone application can utilize your restify node.js backend to handle the model synchronization. You should have plenty of control to setup the routes via restify in a way that makes Backbone happy.
I use for ap in backbone yeoman https://github.com/yeoman/generator-backbone and you use it with node.js too
There is also Node Cellar Source.
There is not much explanation about the code, but the app is simple enough to get started and understand the basics layouts of node / backbone
It is, i think, just between an 'Hello World' code and a full app.

the backbonetutorials.com restify one is out of date. It's best to use express, especially if you plan to do any authorization. It's also more widely used
This is a comprehensive tutorial on rolling your own blog with Nodejs, Mongodb and expressjs http://howtonode.org/express-mongodb It's old but with a little effort you can get it to work and learn at the same time
This ebook could be useful (it's on Backbone, but uses Node for the backend):
