I would really just like a hint or a nudge in the right direction. I feel pretty comfortable with irreducibility over a single variable, but I haven't been exposed to many multivariable questions.
Thanks for the help.

Yes: see it as $f(X)\in (\Bbb C[Y])[X]$ and apply Eisenstein with the prime $Y-1$.
