16x2 LCD translation for SSD1306 128x64 OLED

I am currently working on a project to create my own pixelstick google search DIY PIXEL STICK or check out http://mrossphoto.com/digital-light-wand/.

Anyway I didnt want to use the LCD and figured an OLED would be a perfect fit. This is also my first foray into Arduino. Little did I know that it would be more difficult than I thought.

I am trying to work out how to replace the code for the LCD to work for the OLED. things like

// The Main Loop for the program starts here... 
// This will loop endlessly looking for a key press to perform a function
void loop() {
  switch (menuItem) {
    case 1:
      lcd.print("1:File Select   ");
      lcd.setCursor(0, 1);

I think I understand that, replacing those lcd parts with display.println("1:File Select "); etc work but part where it talks about turning off and on the LCD backlight do not pertain not sure what I would need to do there.

The full list of code can be found at here

if anyone is interested in shedding some light or helping me out I would be greatly appreciative and once I am done I will be uploading and sharing the sketches etc...
