The RS line is the command/data line. High being equal to data and low being equal to command. If you tie it to low, it would never work. Take a look at the examples for LCD iniatilization in the LCD datasheet.

I would recommend that you try the 8-bit mode first and then after you make it work move on to the SPI mode.
