Answer 1

To use iconImageSize property it seems you have to use layout default#image and provide your image.

myPlacemark = new ymaps.Placemark(myMap.getCenter(), {
        hintContent: 'A custom placemark icon',
        balloonContent: 'This is a pretty placemark'
    }, {
        /**
         * Options.
         * You must specify this type of layout.
         */
        iconLayout: 'default#image',
        // Custom image for the placemark icon.
        iconImageHref: 'images/myIcon.gif',
        // The size of the placemark.
        iconImageSize: [30, 42],
        /**
         * The offset of the upper left corner of the icon relative
         * to its "tail" (the anchor point).
         */
        iconImageOffset: [-5, -38]
    }),
