Thanks, I considered that just now, but this question belongs to a section well-prior to covering the residue thm, in the CIF section. So I suppose it should be solvable using that...

Ok, decompose your the denominator into and decompose this using partial fractions and then from there apply Cauchy's integral theorem.
