The first question. BIG HINT: what you are looking for is how to read the CGI headers and find what page has referred the browser to your script. IIRC the variable is HTTP_REFERRER and you should be able to get it off the %ENV hash.
I believe if you'll look at the spec, you'll find that it's actually HTTP_REFERER.
