As far as crew ratings, you would have to go to the campaign files, in that you'll find many dated files, such as 41a, 41b, and so on. You'll also find files for battles, invasions, etc....if you right click on one and open with notepad you can find a line for each group and each ship. You have to adjust the rating for each ship. With RSRD is can be 100s-1000's depending on how much you want. 1 is poor, 4 is elite....commonly used is vet which is 3..
They're numerous files that adjust the ai in the cfg and library
