Start with a baseline, but for all the parts you have listed the only way is to test and tune...You forgot to mention your base timming, that also plays a big role in fuel pressure....
What fuel pressure are you running now?...Are you detonating?...
If you're not sure run rich, it's better safe than sorry...
