You need to "terminate" the instance.  See
http://docs.amazonwebservices.com/AmazonEC2/gsg/2007-01-03/cleaning-up.html#terminating-an-instance
-- there are two ways to do so.  One is, as you described, to run
"shutdown -h" from within the instance, the other is to run
"ec2-terminate-instances".

You can check on the status of your instances in either the web UI or
via the command-line tools.  Either will tell you if you have any active
instances (for which you would be billed).
