Wow, great idea :) This really resonates with me a lot as I am currently doing the same, focussing heavily on my chakras.
Your stack sounds great as it is. Great choices! 
I actually love the Alchemical Garnet especially :) I would personally put it after the chakra audio series.
For a later time, once these have settled and you want to expand your stack to an intermediate or advanced stage: I would recommend to take a look at https://forum.enlightenedstates.com/t/alchemical-zircon-and-danburite/21486?u=kay, as it says in the description that “It is associated with all the chakras and can combine their strengths by aligning them.” as well as https://forum.enlightenedstates.com/t/new-release-vibration-of-creation/1387?u=kay, as it says in there “Chakra growth would be powerfully supplemented by listening to this field.”.
But that would be for much later and please do your own research and discernment from the reviews here on the forum first to see if these are right for you and right at the time. Personally, I have been eyeing at them for the next step for me, but it might be different for everyone. I would also recommend you the Energy Awakening Course at some point.
Good luck :)
