If it's not explicitly stated, then it is the default port number. RFC 2616, which is the spec for HTTP 1.1, says that the default HTTP port is port 80. > 2) Is this TCP port# coming from “/etc/services”?

Of course. You could read one in from the arguments passed into the program as well. Just plug it into the URL, or set the option CURLOPT_PORT.
