You won't need any db9 motor connectors with the G540, as they come WITH it. The G540 also has circuitry for simple spindle speed control and outputs for dc relays to turn coolant pump (Or router motor) on or off.
 
These inexpensive relays are very good for starting and stopping spindle motor, cooling pump, vacuum etc.:

You will need one of THESE 1/4 Watt 3.48K resistors for each 381 or 387:
 
3.48KXBK-ND
 
They only come in a pack of five, so about $1 for 10. With shipping it's about $3.50

Or, in Canada:

You will also need an estop switch, Home/limit switches and a 6 foot "straight thru parallel port cable. These are all available from Keling:

The G540 is so small that many are mounting theirs INSIDE the computer case.
 
Camtronics has a case MADE for the G540:
