1st Question: How do I get the title and subtitle of a selected annotation?
2nd Question: How do I set a custom property such as ‘placemark id’ so that I can use it to fetch details from a datastore?

I do not quite understand the question, can you post a code snippet?
the type of the “o, e” in your sample is (object sender, MKAnnotationViewEventArgs eventArgs).
The “sender” corresponds to the MKMapView that sent the event, but you probably have that already.
The “evt” contains a property “view” which is of type MKAnnotationView which corresponds to the MKAnnotationView that is being displayed.
