Answer 1

Its a key in params. from the looks of things (not for sure, since you provide basically no code or context of the code) it is a string that contains the ID to which you are sending your facebook request. Try looking in the API for the Library you are using.

Answer 3

Documented here: http://developers.facebook.com/docs/reference/rest/stream.publish

The ID of the user, Page, group, or event where you are publishing the content. If you specify a target_id, the post appears on the Wall of the target profile, Page, group, or event, not on the Wall of the user who published the post. This mimics the action of posting on a friend's Wall on Facebook itself.
