Actually, you don't need to answer. I already discovered these answers on my own.
Additionally, I found a glitch:
If the move being foreseen is going to miss, the move your Pokémon uses on the turn it hits will be GLITCHED and show a missing animation. I found this out because I used Fly and switched to another Pokémon, but when I used Dragon Tail, it visually conveyed that Dragon Tail missed, when it still hit. However, when Fly hit the opponent that turn, it missed.
This glitch might actually originate with Future Sight and Doom Desire in regular formats, and it may affect all turns elapsed with the missing Future Sight or Doom Desire, and not just the turn it hits.
Well, with all of that covered, here's what I found:
1. Two-turn moves use both turns immediately, with the damage being dealt two turns later.
2. Metronome counts as a self-targeted move, but it doesn't reveal/choose the random move executed until two turns later, at the same time it uses that move.
Currently I'm testing Double Shock, Revival Blessing, Doodle, Crush Grip, and Roar.
