As Josh pointed out, the domains you listed are redirecting to a page selling that domain. If you are planning to use that domain for your website, you'll need to purchase it first.
If you were just using that domain as an example, then you are correct. The first step is to deploy the DTM header and footer code to the pages you'd like tracked. Assuming you have the Analytics tool installed in your DTM property, you would start to see a default Analytics beacon in the debugger.
Have you installed the debugger yet? If so, are you seeing anything pop up when you run the debugger after visiting your site?
