More entries from PaulZ:

Byte3A seems to be the normal itemset index, though there is something strange about how this works using the default values in the reset dungeons (maybe one of the other unknown bytes is interconnected to this one) Byte3B is the Kecleon shop itemset index Byte3E is the monster house itemset index Byte3D and Byte3F seem to be the itemset index for the contents received from normal and deluxe treasure box Byte42 is the min item density Byte43 is the max item density

Also, ItemSetIndex seems to be the number of rooms in a floor instead.

All of the above have been added on commit a5478eb3424e9e7224139f3358650f99d0bad71b.

New findings by PaulZ

Even more findings by PaulZ:

Byte34 is some sort of limit for the floor height, and Byte35 is some sort of limit for the floor width. Height gets clamped to 18 / Width gets clamped to 20 if values are too low for the room density The game also overrides the room density and generates 3 rooms + stair room
