It sounds like you are very well prepared.
And I think if you get advice from Allan Brown you are getting help from a very good expert. I dont think I can add anything there ..
I think paramecium is really good when they are at that size, – I only recently started to culture that, and I think my ‘fry-surviving-rate’ has grown since then.
Its difficult with those tiny fry to know how much to give, but they are so small that any tank will almost be very big, and I often think that there shouldnt be too far between the foodparticles 🙂
I hatch live BBS once a day – twice is a lot, you must have a lot of happy fish 🙂 …
