i have a few questions:
- should i be putting my code in basic robot main?
- if not, what should my custom .VI absolutely have and what should i wire the end loop too?
- in general what must my program have?
IF you are using the Basic Framework, then your teleop code should go in Basic Robot Main.vi
If you are using the Advanced Framework it gets spread out a bit more.
What you have in your program depends entirely on what you have on your robot. 
The Frameworks have all you need for a basic drive system, but that’s all.
If you put pneumatics on your robot you’ll have to add pneumatics vi’s.
If you want to drive tank-style with two joysticks, you’ll have to modify what’s already there.
You will have to add your own autonomous code in the autonomous vi.
