The concept of fast or slow in audio is a rather nebulous concept that is not well defined.
As caps age, they change their values and hence the crossover points. They can also have other problems like leakage resistance, etc. Not a good thing.
It does sound like the original caps were shot. The trick is to find the right balance.
As for the inductors, the dc resistance is a side effect of having a real part. The higher resistance in an inductive device means more loss in the crossover. Also, the DC resistance of the inductor becomes part of the crossover and can change slightly the crosspoints. I wouldn't worry about this since the effect is small and you can't avoid it.
