Can't help you on WHERE to get a quality tripod and head and Italy, but you can't go wrong with:
Gitzo (if cost is no object)
Really Right Stuff
I've been quite happy with my Vanguard Alta Pro CF tripod too. Not sure if they are available where you are, but they are worth checking out.
As for Macro lenses, I don't have any experience with them, so I'm no help there....
