I'd recommend the Airbus safety library, which has all kinds of useful publications. Many are similar in content to those on the Flight Safety Foundation site, but generally more reader friendly.
This is a guide on flying NPAs as if PAs:

Here's the library site:
Safety Library | Airbus, a leading aircraft manufacturer
Here's the FSF site for approach and landing accident reduction:
ALAR Briefing Notes in English | Flight Safety Foundation
Other good sites where are skybrary.aero and smartcockpit.com
