stress, intonation

Bill: I hear you collect stamps, don’t you, Al?
Al: Yes, I do. I’ve been collecting them for three years.
Bill: Well, I received a letter from Rome yesterday. Would you like to have the stamps?
Al: Yes, please. I don’t have any Italian stamps in my collection.

PLZ tell me which one word in the underlined part I should stress?

[Tdol]

I'd stress 'three' and'Italian' as they are the most important words.
