305 TPI ECM programming

I want to remove the SMOG pump from the 88 Trans AM 305 TPI and would like to know if I need to get the ECU chip reprogrammed? I am also going to swap the 305 for a 350 and want to keep the TPI, I know I need to get the chip reprogrammed for that, but should I also go with larger fuel injectors? 24LB? What about the throttle body should I increase this size to 58MM?
