I did this invasion world quest on 5 alliance toons and received 3 different parts for the gorilla pet with 2 toons getting duplicate pieces.  I then did it on a horde alt and received a part for the spider pet.  It is likely that you need a character on either faction to get both pets.

Edit:  It seems like the turn-ins are repeatable on this world quest.  After you turn it in the first time you are able to go back and farm as much of the turn in material you want to increase the NPCs energy.

I'm incredibly happy about this change.  They actually listened to our feedback on the pet forums!  Six weeks seems fair to me to get all three pets.  Now if only they'd add this in to wailing caverns in addition to the current random drops.
