1. No, the two functions are separate and do not interact - assuming a normal circuit and a high-damping-factor power amp.

2. It sounds to me like you are describing a 6dB/octave crossover with Zobel networks (the series RC across the woofer and the series RL across the tweeter).

The function of a Zobel is to maintain a flat resistive impedance of the driver around the crossover frequency range, since drivers have significant deviations from flat resistance. It is not easy to design a good Zobel, because the driver-specific information you need is neither readily available nor easily measured.
