Potioncat:
I think there are a number of times that the trio between themselves 
refer to teachers by just last names...could be wrong...but I think 
they say "McGonagall" when talking about her. Of course, no fussy 
adults are around to correct them.

I know Harry called Dolores "Umbridge" in front of DD and I think he 
called Quirrell by his surname only as well without being corrected 
in either case.

At the Weasleys, DD is referred to simply as Dumbledore by adults and 
children with no reaction. It seems to be only the name Snape that is 
corrected to include Professor. Perhaps it's as much tone of voice as 
anything, and perhaps in the Umbridge/Quirrell case a bit of 
agreement. 

Hagrid...unless this is movie contamination..asks Harry to call him 
Hagrid.
