We just display what is already on the view. Since you don't know where or how they might drag or zoom the map, I see no point in adding any margin. Just trigger a refresh on drag/zoom end that tells the client what things to add/remove. Keep in mind too that some of your users will be using IE, so you want to cut down on the javascript as much as possible (don't stick up thousands of markers or dozens of polygons with large sets of border points). Although Chrome/FireFox can likely handle a thousand markers without much slow down, it will be unbearably slow for users of IE (at least 10x slower).
