What resistor should I use for the circuit in this tutorial ( http://arduino.cc/en/Tutorial/LiquidCrystalScroll ) and should I wire it to power or ground? Which direction should it face? Thank you in advance for any help you can give on this!

On most displays, wiring vo (pin3) directly to gnd, will give a passable result.
