Answer 1

Try something like this using the graph API
$attachment = array(
'access_token' => $access_token,
'message' => "Hello, here is a post",
'name' => "",
'link' => "http://www......",
'description' => "Write here your description",
'picture'=> "http://www.yourserver.com/images/test.jpg";
);
//print_r($attachment);
$facebook->api('/me/feed', 'POST', $attachment);
Facebook PHP SDK can be found here

I don't know much about php.. but why don't you use FB's java script sdk. It's easy to use.
