You may want to try 2 Firefox add-ons. They are "Firebug" and "Tamper Data".

The "Console" window of Firebug shows the AJAX request and response.

You can then write scripts using the PHP/cURL library to mimic the request.

Do a http request as you normally do for any link or form sumbit but use the url used with ajax. Sometimes you may need to read the javascript source to determine how the url is built.
