If Wo-Chien's "Binding Greed" attack knocks out the Defending Pokemon does the attack effect apply to the new Active Pokemon?
No, the effect of Binding Greed happens to the Defending Pokemon prior to checking if it has been KO'd. It does not pass along to the next Active Pokemon; only the Pokemon that received the attack is affected.
