First of all, there's no problem in taking your time! In the end it's better for everyone and it would be a pity if you needed to stress yourself even more than you already do and that's why do it in your pace and I'll gladly wait a bit longer if that means that the game's quality is higher and the team had more fun doing it.
1. I'm okay with both since they both interest me :)
2. yeah!
3. + 4. auf jeden fall! definitely! I think things like that are really interesting and help us understand more of what you have to do to ensure that this game works at its best. for me personally youtube would be the best
