A question that I have is if the joystick ports are the same why isn't there an option to drive LEDs in all four ports? Does this option already exist and I just don't realize it? Please explain as best you can to me who has a marginal understanding of the default code.

The 4 ports aren't all the same, rather than LEDs, ports 2&4 have connections for the buttons on ports 1 and 3 respectively. That way you can access 8 buttons on one joystick port.
In User_routines.C there is a section called "robot feedback LEDs" I'm not sure which ones the LED drivers in the port use, but it is some of the ones in there.
