Request for wine recommendations

Help!!! I am planning an Italian wine dinner for a group of friends. I have come up with a menu that I can handle without giving myself a nervous breakdown. If only the wine selections were so easy! I have sought help at several local wine stores and of course I have received greatly varying recommendations. One consistent suggestion was to serve a prosecco - three different people suggested serving it with the cheese course while two people suggested serving with the crostini. Only one person suggested an amarone with the sliced grilled steak; while several other people really discouraged it. The person who suggested serving the amarone also suggested serving a barbera with the cheese course (far different from the prosecco idea!). I would really appreciate any assistance! At this point my head is spinning and I have not even narrowed down the types/regions of the wines (other than Italian). Please see my purposed menu below (I am also open to changes in the menu if you think something is problematic). Thank you in advance for any guidance anyone can provide.
