In general there is no going back to the old styles. Contours fewer / typical affects the zoom level transition between when 40' contours are shown or hidden, if you're not at that transition point then it won't have an effect. I'm not sure what you mean with larger, smaller roads though - can you send a link to your map (mark this discussion private if need be)?
PDF labels don't have a white background, but they are printed with a white halo around text. This is in part because line labels are rendered along the length of a line rather than straight; a solid-white background wouldn't really work for that.
