Battery Cables Crossed now the vehicle is having issues?

The battery cables were crossed and now the vehicle is having host of issues as expected. I've checked all the fuses and they all seem fine. Car will currently start but it shuts off when put in gear. I I've scan for the OBD codes and clear them then I scanned the system again and I am including all the codes in that are present in this posting. I'm suspecting that the ECU/PCM is probably bad now along with the alternator. I have yet to take the alternator off and take it to have it tested. I am wondering what else I should check for before moving forward with the repairs. What other parts/modules would be typically affected when this occurs and do you think that I should go ahead and find a replacement ECU module and have it programmed first along with verifying that the alternator still functions properly? Please let me know what you think? Im including all the codes that are currently present in the screenshot.Thank you
