LOAD tells whether unit definition was seen. Units can be incomplete
when they are referred to by other units. E.g. After=foo.service when
foo.service itself does not exist. In this case systemd creates stub
for foo.service and its LOAD state would be not-found. 

ACTIVE tells current running state - whether it is stopped, started,
failed etc.

SUB is unit-type specific qualifier (or explanation) of active state
which hopefully makes it more clear what "active" means (mounted,
running etc). 

I do not think there is exhaustive list somewhere beyond sources.
