The good player asks, "what are the rules and customs at this table?" To them, you must explain how the game works, both that which is written down and the rules of gaming etiquette and give them all the responsibilities they can handle and your game supports.
The simple player asks "what do I do next?" To them, you must explain only that which is necessary to plan their next move and begin roleplaying in earnest—If you confuse them with too many options, they might cease playing and/or think the rules are the game, rather than the platform for the game.
The wicked player asks,"what can I get away with?" By framing the game as a source of loopholes to abuse they subvert the purpose of the game and attempt to hurt everyone else's play in favor of their own fun, and you should teach them their error—or even exile them from the table—as soon as possible.
As for the player too shy to ask questions, you must treat them gently, but try to draw them into the game, asking them "what are you doing now?" and "what would you like to do next?" In so doing, you can allow them to develop into a productive player whether or not they give up their shell..
