That’s fine. The Star Exercise can be done separately from your stack. The key with the exercise is to be consistent with it, so get in the habit of doing it at times of the day when you know you can do it (although not too close to bedtime because it is energizing 
).
That’s a good stack you’ve got there. I personally be inclined to do the Acu-Automaton before Mana Circuits but I don’t know of that makes such a big difference one way or the other. Play around with it and see what you like best.
When it comes to the 3 Treasures in this sort of application, the more mainstream order would be Jing first. (You could do Shen then Chi, given your application, afterwards or the more classical Chi then Shen.) Jing first gives a place for your Chi to be. It’s similar (although not technically the same) as the grounding you’re wanting.
Since we’re talking about my preferences, I think I’d do The Internal Alchemical Crucible (since we now have multiple Crucibles 
) after the healing of Acu-Automaton and before the 3 Treasure. I personally would put Ojas after the 3 Treasures but before the Microcosmic Orbit.
I thought you wanted to ground this but I don’t see any grounding fields? Automated Grounding, Schumann Resonance, The Tree Experience–pick one.
