Server address and permissions

Currently, my installation of mySQL only supports connections to "localhost". How do I configure it to support connections to mydomain.com?

Secondly, I am building a web database using mySQL and wish to create one user for all requests to that database from the web. And then a second user for admin of that database. What is the easiest way to accomplish this?
