You're on the right track: 159,000/(XO freq. in Hz) X Driver Imp. in Ohms= 2.28 uf, and 2.48 uF is a standard value which is probably close enough. A 0.47uF cap would indeed give you a XO freq. of 42K Hz, and it's difficult to make any sense of this in the context of the system you propose.
Try it and see what you think. I would add an inductor to make it real 2 way crossover: L (inductor value in mlliHenrys)=159.155 X Driver Imp. in Ohms/XO freq. in Hz. Note the decimal point in 159.155 here, and the comma in 159,155 above. You could try it both ways as a parallel 6 dB crossover or as a series 6 dB crossover, the parts values will be the same. I'd go series, but that's just my take on it.
BTW do you hear much from Paul Butterfield down Orlando way? Tell him we miss him here!
