4)"Light Wooden Armour" (for units) should have the costs for "I" & "II" And "III" & "IV" swapped, since these pairs are identicle except for organics cost (it is higher for higher armour, but more advanced armour should be better AND/OR cheaper not neither!)

I do not see the problem? I costs 8, has 3 HP. II costs 7, has 3 HP. It gets cheaper with the tech advance. III costs 8, has 4 HP. More expensive but stronger. IV costs 7 and has 4 HP. It again gets cheaper compared with III.
