Specifically, have alook at this PDF document, entitled
"MK V and MK VII - Enhanced Ground Proximity Warning System (EGPWS) and Runway Awareness Advisory System (RAAS) Pilot Guide"

I found it very useful for explaining some of the 'darker' corners of GPWS.
It is 6.61 MB so be patient and wait for it to download.
