Pocket wizard ships with several cables....but not a PRE RELEASE cable....they average around $50
based off what camera you have.
Yes..the pre release button is a must as he stated.....I use this setup (Canon version) on the starting line of drag racing scene...works great
For the trigger...you could get the Mini....it will trigger all PW units...very small...but it don't have all the bells and settings of a Plus III. But just for a trigger...works great!!
