Humanoid creatures are easy - they're just NPCs with altered stats.
For the following creatures, I'd add two types of armor:
Chain, TL1, Cr250, treat as Mesh against melee or thrown weapons and as Jack against ranged weapons. Weights 4000 grams, and, unlike modern or Jack armor, counts against the Encoumberance limit.
Plate, TL2, Cr1,000, treat as Cloth against melee or thrown weapons, as Mesh against primitive ranged weapons and as Jack against modern firearms. Weights 10,000 grams, and, unlike modern or Jack armor, counts against the Encoumberance limit.
Now, on to the critters:

* A gold coin weights 10 grams; how much woud it be worth in Credits?
** Are there stats for an axe in any CT book?
*** Treat as Chain, but weighting only 2000 grams.
