When you change pages in the Napili template, there's a spinner that displays. It's a white rectangular box with three animated dots. Is there an event I can fire through a lightning component that will display that spinner, or some other way of displaying the spinner?
Note: looking through the auradocs documentation doesn't seem to indicate there is a standard event for displaying the spinner.
The Options that we see in the Select Post Destination is based on the Navigational Topics .
You will need to add some Navigational Topics to see the Options there .
Take a look at screenshot from one my sample orgs
Here is good old blog from me on how to set these
Use the force:recordEdit component
Generates an editable view of the specified Salesforce record.
A force:recordEdit component represents the record edit UI for the specified recordId. This example displays the record edit UI and a button, which when pressed saves the record.
You may have to use it in combination with a modal window as I am not sure the component generates the modal on its own or opens in a new window

You can do this by running your own JavaScript function (from within the controller / helper of a component) when you wish to trigger the event.
To show the spinner, you can use:
document.querySelector('.siteforceSpinnerManager.siteforcePanelsContainer').classList.remove('hideEl')and to hide it again, you can use:
document.querySelector('.siteforceSpinnerManager.siteforcePanelsContainer').classList.add('hideEl')
