Answer 2

To get map coordinates, you should use the Map.getBounds method : https://tech.yandex.ru/maps/doc/jsapi/2.1/ref/refe...
If you do not have a lot of objects (it is possible to download the minimum information about all objects per request) map - maybe you should think about objectManager( dock ). There is clustering and a convenient event binding out of the box.
