BBC NEWS - Guide to Key Changes in Space Shuttle
This BBC website has an excellent overview of the modifications to both the shuttle and its working practices:

Introduction:
In February 2003 the space shuttle Columbia broke up during re-entry into the Earth's atmosphere. All seven crew were killed.
The accident was caused by insulating foam from the external fuel tank breaking off during launch and damaging the wing. This allowed superheated gas to penetrate the craft during re-entry.
Since the accident, NASA has modified both the shuttle and its working practices, based on 15 key recommendations from the Columbia Accident Investigation Board.
The aim of all of these changes is to cut the risk of damage from debris, improve detection of damage should it occur, and develop ways of making in-flight repairs.
