Answer 1

If you don't get any errors after the first item.save() method and the item is correctly created you should be able to get the Id through item.getId() function.

Using the example you refer, and remember what Bart points about asynchrony, you can listen to save and savefailed events on your item:

var item = $models.createNewItem($const.ItemType.COMPONENT);

//[...]

function onSaveError(event) {
    $log.error(event.data.ExceptionDetail.Message);
}

function onSave() {
    $log.info("Item's Id: " + item.getId());
}

$evt.addEventHandler(item, "load", onLoad);
$evt.addEventHandler(item, "savefailed", onSaveError);
$evt.addEventHandler(item, "save", onSave);
item.load(true);

So because asynchronous execution you can't write your code like this:

item.save(true);
var Id = item.getId(); //it's going to be undefined because save function is asynchronous
