On point 2, it does not just cost Logistics, but also regular production to get back to mobility an infantry unit.
I believe it's 5 logistics and I do not remember the production value, BUT you can easily discover that. Start a new game, note how much you have stockpiled of Logistic and Production Points. Turn an infantry static. Check again your stockpiles. See how they changed.
Remember cost is proportional, Infantry Division is worth X, Small Corp roughly 2X (with roundings), and Large Corp 3X.
Thanks, Italy only has 1 PP so that's it,
