#18: Yup, you are right. Figures that I would miss that detail. :)
There really should be a separate "benched" section for servants that acts as a sleeping space while they are away from the mansion.
#21: The item list, on the left. Anyhow, I figured it out - I loaded up a savefile after booting the game, and removed Anaryis's rapier. It was listed as gold. I got some cursed blades, did my usual thing, and removed her rapier again - green. Did it with a living armor, and got the same result.
With further investigation, I found that the text color in the item list is dependent on which storage area you are in. While in personal storage, all gold items are marked green, but will have their appropriate color while kept in the mansion inventory.
