Got an Ed30 myself, from memory the only things over and above the 200PS version were:
extra 30PS, obviously

1/2 cloth 1/2 leather seats (not available on other GTis), front seats heated
2-zone climate control as standard
R32 darkened rear lights
colour-coded bottom skirts (or whatever they're called)
Edition 30 logoing and golf-ball gear lever
I think the Pirelli also had rear tinted windows as standard.
Other than that, the Ed30 and 'normal' MkV (if there is any such thing of course - all GTis go to heaven) were configurable with the same options.

PS - forgot to mention the Pescara wheels. Can't remember what the Pirelli's wheels were called
