hide setting boxes

is there a way i can hide the ticker mode and ticker type boxes in the newsticker page so the client cannot change them, i’ve tried using display:none as custom css but the plugin overrides it.

Also the scroll settings under screen options cannot be hidden, as soon as the page is refreshed they reappear, how can i hide these.

thanks.
