Try asking the developers in the cado-nfs mailing list, they are very responsive and I know they have thought pretty deeply about cofactorization strategies.

For extra credit: given a rational and algebraic pair of numbers to factorize, determine as fast as possible if it is worth the effort to try factorizing both.
