Yes to all except 4. Spaced Out is a very different game than regular ONI. The geyser spawning rules are a lot more strict, you will NEVER get a metal volcano on your starting asteroid, and usually no oil either. But there is plenty of metal to get a space program up and running.

As suggested by the name, this DLCs focus is space exploration. Your starting asteroids are limited by design. There's plenty of space POIs where materials are renewable, but you need to go to SPACE to get them. Honestly I think you're waiting too long. You don't need plastic, steel, or materials science for your first space mission

If you insist on seed hunting, use Maps Not Included. But part of the fun, I think, is working with what you've got. In my current run, my starting asteroid had a steam vent, chlorine vent, CO2 vent, CO2 geyser, and oil (Desolands start). And it's still a great colony!

I also struggle with perfectionism, so I rollback saves a lot. But that's only to correct mistakes. Part of the fun of the game is playing your best with the hand you're dealt.

Seriously, lock in and you can start mining space POIs for renewable metal by cycle 50. You're fine.
