I have it entered as....
Spells - Book Name
> A - Book Abbreviation
>> Spell Name
> B - Book Abbreviation
>> Spell Name
Don't do the spell level in the name. If you do that the spell won't link in any of the content you create as developers won't be using that naming convention.
I would put that in the prefix or suffix.
