You could order the parts from Mopar, but I wouldn't recommend it.
Far cheaper (and often better) similar items are available through several of the zillions of aftermarket companies that specialize in Wrangler customization.
I have the black appearance package on my 2010, and I like it. But I'm sure I overpaid getting it straight from Jeep like that. With limited exception, it's safe to assume that any factory ordered cosmetic change to the Wrangler can be done aftermarket for much less.
