1: Is a visual reference required?
No. As long as you can de0scribe the character well enough that I can visialize it I don't require a picture. I just prefer them.

2: Do I have to use existing lore for a mythical creature, or is a custom version acceptable?

Depends on the creature and how much your lore differs from what I know. If your creating a new creature you'll need to have alot of lore.

3: What level of detail is required in backstory and description?

I need enough of a backstory to understand why their joining the BOSA.
