Although I'm using Snow Leopard, my guess is that the procedure for faxing in Lion is not too different. In the Finder, go to the Help menu and click Mac Help. Select Mac Help in the new window and type Fax in the search box, then press Return. You'll get a number of articles about faxes. I chose Sending A Fax and it described the procedure.

Since I neither use Mail nor get my email via the Internet (although I could), I can't answer the email question.
