The LCD display comes in 2 sizes and with or without an i2c adapter.  Make sure you get the one with the i2c adapter pcf8574t as it saves a lot of time and all of these instructions are geared towards the adapter.  The size doesn't matter a whole lot, but I typically only use the 2 lines by 16 characters (LCD1602).  The other size has 4 lines and 20 characters across (LCD2004).
