OK I got everything plumbed in on my duetto III, now a small question. When the machine is not running the pressure regulator read about 65 psi and the gauge on the machine reads about 4.2 bar. when the machine is running the pressure regulator reads about 25 psi and the gauge on the machine reads just a tad over 9 bar. Is this static pressure to high or is supposed to be like that?

If that's the type of regulator you have then yes the static pressure reading in a no flow condition.
In truth the pressure shouldn't change hardly at all when the machine is running, because the flow rate is quite low, however they type and price of regulator you have dictates how well this all works. The main thing it needs to do is to maintain a reasonable pressure within the 1.5-2.5 bar range, even if the pressure upstream of the regulator moves to 5 bar....that'[s the whole point of it.
Yea, those are the instructions I followed. Flipped up the brew lever and adjusted the pressure on the regulator to ~30, when i turned off the machine the pressure on the regulator goes up to ~65. Should I just set the pressure to ~30 with the machine not running?
