Iaquinta, especially in his first season, started many matches from the bench, and if we count only the starts, then his average will be even closer to Trez and Del Piero.
As for the assists, in the last two seasons (not counting 2007/08 for which I don't have data) it's like this:
Del Piero 11 assists
Iaquinta 7
Amauri 5
Trezeguet 2
I don't know what was the original discussion between you and Andy about, but if it was some comparison between Iaquinta and Amauri, then it's obvious that in front of the goal (scoring+assisting) Iaquinta has been more useful than the Brazilian.
If it was between Iaquinta and Trez, then they're almost the same, with Trez scoring a little more on average, while Iaquinta assists more.
