Ok I've changed the order of things in my episode outline. It's now a kind of 'descent into darkness', beginning in peace and ending in horror.
1. Storm of Uinen.
2. We see Círdan, see the life of the Falathrim, their settlements, ships etc. This is long before the Kinslaying and certainly long before Círdan hears about the crime. He has completed a new large ship. A visiting Sindar - let's say it's Beleg - is impressed and says he'll make sure to tell King Thingol about it. 'Yes, tell Elwë', Círdan says.
3. We go to Thingol and Melian, and their court. Luthien dances under the stars and Daeron sings. (Luthien has to shine from the very beginning, we have to fall in love with her at least a bit even if she's not going to do anything for ages and we will hardly see her (but we will show her reacting to Menegroth etc). Daeron has to be a star. In these times of peace, he will (well, apart from Thingol and Melian, and Luthien), be the person at court that people talk about and admire. This will put him in a position which makes him develop fantasies about himself and Luthien. We should at some point learn that he has invented writing.)
4. We see Eöl who has some kind of contact with Mîm. This is to establish that Eöl has contact with dwarves of all kinds, and to show that Mîm lives in what is to become Menegroth, and to show two loners. They don't have to be friends - in fact, I'm not sure that's within their capacity. Also, since the Dwarves of the Blue Mts. and Eöl will be friends, it is perhaps best if Eöl and Mîm don't like each other - the petty dwarf and the Ered Luin dwarves will not be friends and a friendship between Eöl and the Ered Luin dwarves would be tainted by him befriending Mîm.
5. Angband: (Not sure how much of this happened earlier, I missed a session) SSNOP details, orcs being prepped for release. Morgoth does some management by fear, letting his servants know that no one has a safe position: Sauron loses his job, is sent to find out what happened to Ungoliant, but also and perhaps primarily to map the Sindar movements, where they live etc. Boldog is put in charge of the orc project. His position is under Gothmog who is made operative general of the army that will be created. (I don't think a lot of time has to be spent on Angband. Boldog's relation to Mairon is probably that he thinks Mairon is a loser and he himself a winner, but they won't have much contact at this stage. Mairon is filled with the desire to prove himself in Melkor’s eyes and hate against Gothmog. (By handling Mairon roughly, Morgoth actually provokes Mairon to step further towards a complete fall.)
6. Beleg and Mablung encounter orcs for the first time. The two elves happen to come across some sorry looking beasts wandering - early versions of orcs. These orcs run away.(Where is this - close to Eithel Sirion?) Suddenly the starlit dark is disrupted by three volcanic explosions to the north. The Thangoridrim peaks are created. The time of peace is over.
