Anyone know how much current the DS outputs can sink or source??

See section 3.1.6.2 of the control system manual.

See http://www.usfirst.org/frccontrolsystem and Chapter 3 Component Data Sheets of the Control System Manual.

The DS digital output pins are driven directly by 5V transceiver (SN74LVC4245A device). Be sure to use caution as each pin can source/sink more than 40mA. It is possible to damage the device if too much current is driven on a single pin or the total current supplied by the device on all pins is excessive. Best practice should be to use a limiting resistor to prevent external loads from drawing excessive current, especially for LEDs, be sure to use a series resistor to limit the current.
