The critical components are those in series with the drivers. I'd consider the shunt inductor in the tweeter circuit fairly critical too. The Zobel isn't critical, although I would try a pseudo-first-order filter on the woofer, since you're near mechanical rolloff. That will make the total crossover slope higher than just the electrical filter slope. You don't need a Zobel with pseudo-first-order crossovers, it's just a single series coil.
