I voted Luca Toni - he's having a good season with Bayern, and should he start this Euro I am sure he will be more consistently on target than WC 2006 (which in all honestly I expected him to achieve at least 4-5 goals!).
Marco Boriello is a fresh change, and he should bring in some unexpected surprises.
The third striker, the bench striker, or super sub, would have to be Iaquinta. I still think he has alot to offer for the NT.
So those are my 3 votes.
Although I like Tomasso Rocchi, he can be a good dribbler with on target finishing; but isn't always that consistent.
I like Gila as a player too, but I'm afraid he's not reliable enough...
