A possible idea for the Encyclopedia in the FAQs section could be
to include the Techs/Talents each monster comes with directly
from the Encyclopedia. I know it would definitely be helpful for
combining. (Though, with the addition of feeding monsters Slate
Fragments to gain certain Talents/Techs, it might actually not be
all that useful).

Every book monster is identical. The techs they start with are hard-coded. (I don't see how this information is helpful for combining since you shouldn't be combining book monsters at all.)

This information is VERY tedious to enter, but the perfect guide has it all. Here is a sample of what the perfect guide has for every monster:

#	Name		Main	Sub
# 160 (158 US)	Flazer		Tiger	Joker
Regen:
Draw	Yes	Speech	No
Text	Yes
Stat	#	Gain		Growth	Normal
POW	157	High		Lifespan	3
INT	67	Low		Techs	3,4
Skill	132	Normal		Breed Trait	Hi Power
Spd	127	Normal		Battle Trait	Fury
Def	78	Low		Battle Move Spd	5
Life	100	Normal		Guts Regen Rate	3
				Battle Resistance	1

Now, do you think I want to make that chart 270 times? =)

you could do a flat-text version with the bits in columns.
