Doesn't the status change depending on whether the request was successful? Why explicitly set it to 200?

Does it make a difference whether I use port 3000, 1337, 80, 8080, 4567, etc?

The status is set to 200 to indicate that the message you are sending is the result of a successfully handled request. If you were sending back an error message, you'd use a different response code.

The port number chosen must be one not already in use by another service on the same machine. Plus, it's a good practice not to use one commonly associated with a specific service unless it's what you are providing. A list of commonly used ports can be seen on this Wikipedia page.
