Here's a table of some properties of monsters.  I primarily made this for myself, but share it in case it interests you.

Legend.  The first three columns might contain errors.
 - Column 0: H if the monster can wear boots and helmet and gloves, C if it can wear helmet and gloves.
 - Column 1: h if the monster can wear body armor.
 - Column 2: T if the monster can wield items.
 - Column 3: L if the monster is living.
 - Column 4: f if the monster is breathing.
 - Column 5: q if the monster is an animal, D if it is an item-user (not mindless, not animal), k if it is a wand-user (not mindless, not animal, has hands)
 - Column 6: playable race of the monster: Q for elf, h for dwarf, G for gnome, o for orc, @ for human.
 - Column 8: symbol of the monster.
 - Column 9 and 10: color of the monster, in hex.
 - Rest: name of monster.
