Help with Roadrunner Hardware Mapping
Jumping right in is a very difficult way to learn in this program. I would highly suggest reading this https://github.com/alan412/LearnJavaForFTC/blob/master/LearnJavaForFTC.pdf to get an overview of the basics you will need. It's not very long and is most of the knowledge you will need for this competition.

Custom tflite model implemention help
If you're using OnBot Java, you can do this. There's an OnBot Java example OpMode which is named something like "ConceptTensorFlowObjectDetectionWebcam". You will need to change the TFOD_MODEL_ASSET and LABELS fields to work with your model. In the example, it will setup a Vuforia instance and TFObjectDetector instance for your webcam and model, show you how to repeatedly get recognitions, and show how to read data from those recognitions. Link to the code here: https://github.com/OpenFTC/Extracted-RC/blob/master/FtcRobotController/src/main/java/org/firstinspires/ftc/robotcontroller/external/samples/ConceptTensorFlowObjectDetectionWebcam.java

Is it possible to replace the OS/software packaged with the REV control hub with something less restrictive?
While the control hub OS is closed source as far as i know, nothing stops you from "using the hardware how you want". The rc controller app source code is fully viewable from the source AARS and can be found in: https://github.com/OpenFTC/Extracted-RC , that might be an start if you wanna modify something.

Where can I find the com.qualcomm files in the folder
Yes, as another comment mentions, these are the sdk's dependencies. You can go to the source class of something by ctrl clicking or putting your cursor over something and pressing f4. Also, the github repo https://github.com/OpenFTC/Extracted-Rc here has all the dependencies extracted if you want to browse them.

First day of using Vim
Also if you'd like to take a look, there is no way to achieve the behavior that he wants (which is to run a blocking loop until the Robot Controller sends an initialization command) without reverse logic. waitForStart() as he mentioned is not a flag. It's a blocking function. https://github.com/OpenFTC/Extracted-RC/blob/6720cf8b4296c90b6ea4638752c2df4a52b043b9/RobotCore/src/main/java/com/qualcomm/robotcore/eventloop/opmode/LinearOpMode.java#L60 Also waitForStart() itself uses !isStarted().
