Number 1, No if you have the same color you put it in the same layer. If you had a bike that's blue, and a helmet that's blue, they'd print all the blue in one color. What I'm saying is if the blue is the same.
If you have a sky blue, and a navy blue those are two different colors.
2) Gradients and like 50% opaque colors: They can be made on the same screen (color), but it depends on the screen printer. Some screen printers want them on separate screens.
3) As far as which to order first is up to the company you're buying it from. Ask them what they prefer. They all start screen printing with the base first, but they don't all screen print the colors in the same order. I.E. Darks to light or light to dark.
We do th base and end with borders if they have one.
