Installing the MAMP package was the right way to get started, and to quicly and easily start using Moodle on your own computer.
Once you have built something that you want other people to see, you will need to transfer the Moodle course somwhere else, and you can do that using Moodle's backup and restore system. Phil gave you some options for getting a real Moodle server on the internet.
P.S. I was amused to read the title of your post, and then see acronyms like IDT and LMS in the first paragraph, so we all use technical lingo. It is just that the technical lingo that we are familiar with is not scary.
