I think I am going to pick up some extra screws, nylon standoffs and spacers, washers, maybe an XT-60 connector, female-female servo cables, and some extra 5030 props for it.

And as mentioned above, I am getting 5030 props for it. It comes with 16 of them, although I am unsure of what brand exactly. I think ill pick up some Gemfan 5030 props on amazon.
