One Zobel network before branching off to the woofers seems like the sensible option. Although I might be tempted to use one per woofer to avoid the thinking required to determine the values for a "composite" driver. Or I'd hook up the IMP/MLS and use trial and error.

Two 8 ohm woofers in parallel gives you 4 ohms, so you should design the low pass filter for 4 ohms.

It's impressive how well even a rule-of-thumb Zobel improves the electrical response of a passive crossover.
