Joystick Controller Help

[jhellr13]

Next month, our team is going to our middle school to show the students our robot and let them drive it around. Our current drive set up is with two joysticks. 1 with the arm and 1 for the arcade drive. We also have a logitech game controller laying around, and I might let the students drive with that so both joysticks are on the same controller. Also, most middle school kids play video games, so the feel should be easy. I have some questions with this though:

1) How do you program the two joysticks on the game controller separately to maintain one for the drive and one for the arm? I've only used a joystick so I am slightly lost.
2) On our drive joystick, we use axis 3 to control our speed. If the students are driving with the game controller, am i still able to control the speed even if I am not driving the robot on my joystick?
3) If the students are driving, and I quickly need to alter their driving, can I move my joystick to change direction, etc. or will the conflicting demands from both joysticks cause a problem with the jaguars?

We are using LabVIEW. Thanks for the help
