I find the LiveHTTPHeaders extension for firefox to be very good for
this kind of thing.

It gives you a realistic (as opposed to theoretical) view of exactly
what is being sent between the browser and the server. Networking
details that you listed like the mac address are handled in the
networking layer rather than by the browser, you probably also want to
look up TCP/IP headers.
