I dont think there are any other differences between the two versions.
I dont know if this is a mistake or if I'm just reading it wrong but in the fourth book it says:
' Cedric's body was lying some twenty feet away. Some way beyond him, glinting in the starlight, lay the Triwizard Cup. Harry's wand was on the ground at his feet.'
this to me sounds as if the wand is at Harry's feet but later on it says:
'Wormtail walked out of the circle to the place where Cedrics body lay, and returned with Harry's wand,'
which says the wand is at Cedrics body which would mean it was a mistake but then again I could be reading it wrong.
