1) Learning Python-fu is somewhat faster,
2) "(batch-auto-fix "C:\Users\parkinsj\Desktop\GIMP_Batch\img*.jpg")" -b "(gimp-quit 0)": nested quotes and backslashes... the problem isn't Gimp, but the Windows shell processor (CMD.EXE). You likely have to escape the quotes around "C:\Users\parkinsj\Desktop\GIMP_Batch\img*.jpg" because they are inside those that delimit "(batch-auto-fix "C:\Users\parkinsj\Desktop\GIMP_Batch\img*.jpg")". I don't remember if this is done by doubling them ("") or by putting a backslash (\"). Your error message indicates that the quotes where stripped out to the input string so Gimp no longer sees a string literal.
Then use (gimp-message ...) to print the values of the arguments you received and se of this is what you expect. No point in debugging code that doesn't receive proper arguments.
