Do you have a specific class and sanctioning body in mind? If you're running with the SCCA, those modifications will bump you up a few classes. I have been running in Stock class all season and the car is a blast on an autocross course within the Stock-class rules, I definitely recommend it.
If you don't care about class and just want to mod the car, it really just comes down to what you want to do to it.
