1) Will Bloodlines support the three standard types of damage (Bashing,
Lethal, Aggravated) found in the World of Darkness? And if so how will they
be implemented?

Yes, Vampire: The Masquerade - Bloodlines has all three types of damage.
The end result is similar to the PnP version. Vampires are nearly immune
to Bashing, Lethal poses a bit of a problem, and Aggravated is extremely
problematic. Bashing damage is done by blunt instruments, Lethal is dealt
by bladed weapons and firearms (though interestingly, Vampires treat
firearms as bashing damage) and Aggravated is caused by fire, huge amounts
of electricity, and some of the Disciplines.

2) Will there be powers that allow a Canite to fly, will there be a maximum
height you can travel?

Unfortunately, Cainites will not be able to fly. However, they can jump
some good distance, which is regulated by their Strength and Athletics. I
can't give you any precise numbers at the moment as we're still balancing
the gameplay.
