In regards to the transformation question, you have to be over the powerlevel with turbo (the aura) off. I think you can fill the CF bar and have turbo on, but it won't let you transform since your base powerlevel is still too low. That's probably what happened. Or maybe you accidentally unbound the transformation key.
As for the bots, I think the = key brings up the bot menu, and from there you can tell the bots how to behave. There might be an option in the controls menu to choose what key brings up the bot menu. If not, there's definitely a console command. Maybe try typing bot_menu in console?
