No, they don't have to eat or drink - this could be explained by a dust-induced mutation, since dust seems to have magical properties. My headcanon theory involves a man-made apocalypse by dust, including a lot of cross-breeding and dust-infusing experiments.

You make a good (and funny) point about an army of Migikarp. Here's a thought - what if, by interfacing one's soul with the creature being tamed, it left the creature with an Aura of their own? A regular Beowolf is no challenge to anyone with decent training, but if that Beo had an Aura and increased intelligence, it could become a problem, even by itself. Of course, that would lead to all kinds of other questions, like: what would happen if a Grimm tempered in this manner were to develop a soul of its own?
