If you want to start an Italian section, you can just create Italian versions of pages. Check the other languages for examples and check e.g. http://en.wikipedia.org/wiki/Help:Editing for instructions on how a Wiki can be edited.
Check e.g. with user Daggerstab if you have special questions, as he is more busy content wise.
Concerning your questions, I'd suggest to ask them to Alexwolf or Daggerstab. They are working on the actual program and are more active on the contents of this Wiki. I'm more or less the 'janitor' of this wiki ;-)
