Yes, you can access the Raspberry Pi's I2C pins through pins 2 and 3 (which are labeled SDA and SCL, respectively) on the Dual MC33926 Motor Driver board. For more details about the I/O connections between the add-on board and Raspberry Pi, see the "Pololu Dual MC33926 Motor Driver for Raspberry Pi schematic diagram" under the "Resources" tab on its product page

That sounds like a really cool project! The Zumo 32U4 library contains additional component libraries that are not included in the A-Star 32U4 library, specifically the L3G library and the LSM303 library, which conflict with the PololuRPiSlave library. To get the AStarRPiSlaveDemo sketch to compile with the Zumo 32U4 library, you need to remove those two component libraries.
Blog comments are not the most appropriate place for troubleshooting, so if you need further assistance, I suggest continuing the discussion on our forum.
By the way, we would love to see some pictures of your project and to hear more about it! If you have more progress to share, feel free to reply here or post about it in the "Sharing your projects" section of our forum.
There is no special entry for the Pololu USB AVR Programmer v2. You should look at the "AVR programming using the Arduino IDE" section of the Pololu USB AVR Programmer v2 User's Guide, which states which programmer entry to use in the IDE.
Blog comments are not an appropriate place for troubleshooting. Please post on our forum or email us a more detailed description of your problem (it is not clear to me what you mean when you say the code "isn't showing up in yellow").
I do not expect my code to be particularly helpful to you because it is so directly tied to the specific design of my robot, but if you post more details about your robot on our forum, including what you are trying to do and the problems you are having, we might be able to give you some general advice to get you on the right track.
You did not include enough information in your post for me to tell what the issue is, but the blog is not an appropriate place for troubleshooting. I recommend posting your issue on the forum or contacting us via email with more information about your setup (e.g. pictures showing all the connections in your system, power supply, code). Please see our Support page for more details on getting technical support.
We separated the AStar32U4 library and Zumo32U4 library into their own repositories on our GitHub page, and I forgot to update the link in my previous comment, which is updated now. Here's the link to see the full Zumo-32U4 Library.
We did not make the robot in this post, and we do not sell it. You could look at the PiBot-A's project page, which is linked just below the "PiBot-A - Obstacle Avoider" video, to get an idea of how to build the custom robot or something similar. The PiBot-A's page contains some code and a list of parts used to make it, which might help get you started. (The project page is written in German, but you could use Google Translate to translate the page.)
Sorry, I forgot to follow-up and post when we added that code to our libraries. You can now find the balancing code inside the Examples folder of the Zumo32U4 library as well as four other examples: RotationResist, FaceUphill, RemoteControl, and SumoProximitySensors.
Unfortunately, the code for the "Balance using the gyro and accelerometer" example (shown in the video) is not available yet. We plan to add it to the Zumo32U4 library soon.
