Help uploading RobotPy code

[nyaculak]

My team was considering using Python for a few projects during the off-season. I downloaded RobotPy-2012.2 from First Forge, and I'm slightly confused about which files I'm suppose to use to upload the code.
0) We should start by flashing our cRIO to C++, correct?
1) I'm assuming I start by adding a main robot code file called "robot.py" to the directory "./robot/py". Am I correct?
2) I looked into the utilities directory and I saw two install scripts. One is called install.py, and the other is called team_upload.py. Which one am I suppose to use? Or are we suppose to use both?
3) For each install script that you are suppose to use, could you tell me which directory I'm suppose to call it from? I don't think we're suppose to run the install script from the utilities directory
4) My team tried to use python earlier this year, but when we uploaded code (through Filezilla), our DS said we had communication, but no robot code. Are there any possible explanations for this?
Thanks for any help you can give us!
