No, motions don't become legislation.  Bills become legislation.  Motions are basically announcements with no binding power.  Someone can stand up in Parliament tomorrow and submit a motion that everybody should wish her dog well because he's sick.  If it passed, it would be formally noted that everybody in Parliament wishes a dog well.  That's it.

Essentially, yes.  A motion is just somebody standing up  in Parliament and saying I believe this and then Parliament votes to agree or disagree.  It's THAT simple.... and you're angry about it.  Think on that for a while.
