Concerning the "directional" part, capacitors used in crossovers are not (or should not be) polarized (directional). They will be either a "film" type (expensive) or non-polarized electrolytic. Radio Shack does not sell the film type in high enough values for use in a subwoofer crossover, but I believe they do carry a limited number of non-polarized electrolytics.
Even better, check out
www.partsexpress.com for either crossover parts or already-assembled subwoofer crossovers at very reasonable prices.
