Wow, you are asking for a lot there. The short answer... yes all of that can be done. The full answer you don't really want to try do you? Go to the default directory --> utilities --> script parser. There you will see all of the AI files and the script parser to compile everything when you are done and the scripts for each Stock empire. Now as to the actual files you will need to change within there? Well I couldn't possibly hope to get everyone of them but you will need to start with Script_AI_GlobelSettings.txt is a good place. You will need to get the one for Construction, Design Creation, and Orders_Ships at a minimum. I know there will be more but the others aren't coming to me right now. Oh yes you will need to define the strategy in the data directory in Strategies and Warp Transit Types texts. Ok that should get you started. See you in two days in the loony bin; assuming you make it past the tears and shock to start!
I'm in room 13, stop by for a game of checkers some time.
