Auto-Login to Facebook, HTTP POST, how it can be done? Options

[LYI]

After a half-year of experience of posting/replying to Facebook messages i came to the need to do that automatically, at least partly. The first problem i had encountered is that i can't login to it from within my own program.

Q1. I would appreciate any suggestions on to how that can be done.
Q2. Currently I can't understand what is happening after FORM Submit button is pressed:

<form id="login_form"
onsubmit="return Event.__inlineSubmit(this,event)"
action="https://www.facebook.com/login.php?login_attempt=1"
method="POST">

- if there will be a function within onsubmit field, then i may investigate it; but there is Event - i simply can not find where to look for code that is executed on submit.
- i had an experience in using HTTP POST with successful login results, where fields with id="email" and id="pass" were sent to the server along with their values; therefore i was expecting the similar thing to be done in case with HTTPS POST, but it doesn't work...

What i have to consider to make a proper HTTPS POST request to server?
