there is only one bulb for the shifter however there are three total bulbs required if you wish to do the courtesy lamps (light by your feet) as well.
the courtesy lights are stupid easy to do and can be gotten to by just looking where the light is coming from.. lol
as for the shifter you need to pull the trim pieces out from around the shifter then twist the bulb base out replace the bulb and reinstall is reverse of removal.
btw- I should note that the light in the glove box and the light for the license plate are both 194 bulbs... I personally have a white bulb in for all of mine
