The food and hygiene items are easy; she copy and pastes from a Superstore on the western seaboard and is able to turn up just about everything. The shampoo and conditioner are blackberry-scented.
Getting Sable's sizes is easy enough (Stella can "visualize" making a tape measure well enough to measure her body in the appropriate places), and there's plenty of places to copy from. For goth and star-themed clothes, Stella copies the whole store contents of several goth and alt-wear boutiques into a large pile on the house's bed, and leaves a letter atop it saying to pile up the rejects for her to vanish.
The formal priestess robe is worth some consideration, but she's not feeling strained right now; she'll take her time designing it when she next needs a break.
She's stocked the house with fresh water in the pantry, but she takes the time to hook up a proper desalinator to the house and get the plumbing sorted out. Missing that detail was sloppy of her, but then, she is distracted. She puts in a wifi router, but she'll have to deal with bureaucracy for satellite internet, since she has no credit card and isn't willing to steal someone else's. She tries reaching to space and discovers she can't put a satellite into orbit herself. That's troubling.
Backup copies of the island to hop between are worth considering. Right now it doesn't represent an excess of work, and the threat is as low as it's ever going to be. She'll make a mirror island a few thousand kilometers to the south, in the rough vicinity of the Marshall Islands, and keep it updated with everything except the people as she goes. Duplication in multiple places is easy like breathing. Once dusk moves further west she'll do a couple in the Indian ocean as well. That way she can just move the people and always have a template to draw from unless there's some form of massive coordinated strike — and if she pisses off the world that badly, she's got bigger problems.
She appears a small office complex from San Francisco on the other side of the (currently quite small) island and hooks it into a similar set of grid hookups as Sable's house. An apartment complex quickly follows.
She might as well green up the lawn a bit while she's here. She copies some sod over. A proper garden can happen when she needs a break.
She writes a note. It ends up being a lot longer than she had planned.
I can integrate parts of real animals into human bodies well enough to grant senses present in actual animals. I've never done it yet — it takes a lot of time and investment — but I checked because you were a fox-girl online and I wondered if I could make you one in real life. It turns out I can. So yes, I can do night vision.
I'm actively doing my best to be as friendly and just as I can, but I'm fallible like mortals are; my mind is not so different from a human's. I will inevitably make slips. A PR account is a good idea, but we'll need someone very competent to manage it. I also don't want to give people the impression that you or any priestess speak directly for me, though. No-one else should have to shoulder that burden.
An official scripture will take time but is definitely important. I don't want to give people the impression they can do just anything they want in my name, which will inevitably happen if I don't have an opinion on the matter.
Your decision to be public or not about being my priestess is up to your judgment. I don't want to burden you with being seen as something holy, or force you to risk your public identity. You might not have an opinion, but your family probably does; do you want them to be inundated with messages from people who want them to help, because they are the world's channel to you, who is a channel to me? Or threatened by acronyms or gangs? Being my priestess is a high-risk job, just like being a UN diplomat or similar... but then, you knew that when you accepted. It is ultimately up to you how much you want to risk; I can't make that judgment call for you.
If you are being open, you should tell people your title is First Priestess. Not High Priestess — that will probably go to someone terrifyingly competent — but First. I chose you because you fit with me and my methods, not because you were useful. The fact you reached out mattered, but mostly because it meant you were like me; always seeking an opportunity to help.
I have made a simple statement of my goals to the United States government, and indeed to several other governments who asked. Copies are attached. I think you understand my goals more or less correctly, it's just a matter of phrasing it for the public.
Two other items, both of which you should keep secret:
Firstly, I keep backup copies of bodies from recent deaths that I cannot repair with my current skills. I have successfully revived several people who I have temporarily vitrified to stabilize them. May I make a backup copy of you to keep on ice and regularly update the brain of from your current one? I wouldn't wake her unless something happened to this you, naturally.
Second; while I wish to keep this secret from the world at large, it will undoubtedly become known to major intelligence agencies that review my actions over the long term. As such, I think I should tell you now. Acting to create miracles from prayer causes physical pain to me when done in the area of artificial light. The more intense the light, the more intense the pain. I do not want this to become publicly known, but I am presently nursing the godly equivalent of a killer headache and I expect it will only get worse the more I act in populated areas. As such... I would really appreciate it if we modified you to be able to see in the dark. This would have knock on effects though — you'd be visibly inhuman thanks to your eyes, and that means you'd become known as my priestess wherever you go, etc, etc, etc. I'm not going to do something so major to you without making sure you understand the implications.
Lastly — do you mind if I use your credit card to purchase a satellite internet account? I expect that in the long term I'll be extremely rich, but currently I have no licit identity to do trade. Doing this will almost certainly flag you as my priestess to certain acronym agencies, though, if they don't already know.
I think that's everything.
