For the solenoid/trigger part you need something like the following:
You'll find the solenoid vi's in:
WPI Robotics Library->Actuators->Solenoid
The blue "Forward" and "Reverse" you get by positioning the cursor over the input node on the left side of the Solenoid Set vi, right-click to get the node menu and choose
Create -> Constant.
Break the wire holding it to the Solenoid Set and copy and paste it wherever it needs to be, then wire them to the proper spots.
