Again, I see no definition of what you mean by accuracy in the result of polynomial multiplication. If you look at the actual algebraic formula for any given coefficient in the result, you see it is the sum of products of coefficients from the inputs, and the possibility of cancellation depends on the magnitude and sign of those terms, and the order and arrangement of the operations. You can rearrange them various ways, but if I want to play some kind of adversary game with you, and you tell me how you are going to compute it, then I believe I can come up with coefficients that will give you answers for particular coefficients that are quite bad.
As far as specifics as to which work on asymptotic complexity is irrelevant, I think that as a first cut you should assume that ALL the published theoretical work is irrelevant to practice. , There are particular authors whose work combines poor exposition, elaborate and unnecessary notation, complicated proposals, non-implementation, and unfounded claims. Note that these defects do not make a theoretical paper unpublishable, or even "wrong". After all, for some n>N the claim may be true, just that N represents a problem size that requires all the electrons in the universe to represent explicitly.
