The idle speed is computer controled, it is not adjustable, you most likely have sludge in the throttle valve and the idle speed control air bypass valve, clean them with carb spray with the engine running.

The high idle speed at start up is normal. As the engine temperature increases, the engine idle should kick down automatically. Insofar as the emissions results, if there were a problem, the check engine light should be on. If it is, take the car to an autoparts store and have the fault codes read. Most parts stores will perform the scan for free. If the check engine light is not on, and the idle question was all you were worried about, you are good to go! Hope this helped and best wishes.
