As far as the Treated vs Coated armours, I'm going to wait for that to be fixed in v1.13 before changing anything.

There is nothing to fix in that regard in 1.13. Check this post and upwards for the decision making process behind the new values.
Royal Jelly is a different pair of shoes now compared to C-18. The jelly provides less armor bonus because it has only bonuses whereas the C-18 comes with penalties.
