It doesn't stack with normal crits and it benefits from IE passive so you can look at it as a normal crit. And no the 140% is BONUS damage so a deceive crit will do 240% of your autoattack damage.

And yes, the passive bonus damage applies to crits. It applies to all damage you do from the autoattack (including on-hit effects like madredsbloodrazor) so it is always ideal to attack from the back.
