I think it looks like a good start, but I suppose I'm biased
They usually just throw in random samples, but if you request something specific I'm sure they'll be happy to oblige.
I've also found their greens to be great. Their "Emerald Petals" (Lu An Gua Pian) and Cloud Mist are a couple of my favorites. I'd also still suggest a Dancong.
Of course you can also always get a handful of samples of various things.
