Sounds like you have the basic theory down.
I would forget about boiling and reducing anything after base has been added. Base should only come into the equation when you are ready to freebase and pull the alkaloids. There is no need to neutralize the acid before reducing. Reducing weak acids is fine, but avoid reducing basic solutions completely.
If you want to drytek it, you could simply dry and powderize the plant material, add minimal water and base that. I'd use lime for that instead of the sodium carbonate. You could pull from that with ISO, naphtha, xylene, anything DMT is soluble in. The downside is you will pull a lot of chlorophyll and other stuff.
If you did reduce the tea to a syrup, make a basic powder and pull with ISO it will be a lot more fuss than simpler methods using naphtha to pull from your basified tea.
A simple clean way would be to do exactly as you mentioned up to reducing the tea to 300ml. Chlorophyll tends to separate during boiling so you could skim it off and discard it. Then base the tea with NaOH and pull with naphtha. Xylene will work but is less selective for DMT than regular naphtha.
I'm not trying to discourage you from doing it jamie's way, it's just that the method is different as it makes use of sodium carbonate and no naptha. If you want to use naptha, just base the tea and rip those alks right out. If you don't want to use NaOH, maybe do the paste. It's just a fair bit of extra work if you're going to use naphtha anyway.
ISO absorbs water from the air too, and thus will bring base into your final product.
And despite having just said ALL that... I bet you could just use naphtha to strip a dry basified powder of it's alkaloids instead of ISO if you'd rather do that. Pulling from filtered, reduced and basified solution would just give a cleaner result, and would also be quicker IMO.
