Well, that is the throw out bearing rattling as far as the other stuff I don't know about but we have done 4 clutchs and it is alot easier to pull the motor than the transmission but we always go out the top just a few ideas for you I would take it back and have them fix it until they get it right some of them rattle and some don't good luck but get them to fix it. By the way it's not hurting anything its just annoying pulling though the drive though and having that thing rattling it sounds like a piece of junk.
