And welcome from me too! I have learned so much from this forum, not only by asking questions, but also by searching old posts. I'll be interested to see what someone with more experience has to say about your dilemmas, but with my limited experience, here goes:
The first couple of weeks of a Cam's life are tricky until, with luck or experience, you get the conditions right
1) Will you still have something eatable? Probably, but it mightn't be what you thought it was going to be like. It will still be cheese!
2) I, too, scrape away blue mold spots, but don't resalt.
3) I pat dry mine with paper towel for the first few days if they are visibly damp;
4) I used to have trouble with mold coming off when I used bamboo mats, now I've gone to plastic its much better. And I flip every day while waiting for the mold to establish;
5) Depending on which part of Oz you live, room temp, even in a mudbrick or rammed earth might still be warmer than the ideal 13 C, +- a couple of degrees,
I reckon wrapping in cheesepaper and bunging in the fridge is a great plan.
And hey, you'll discover that the forum readers LOVE photos! Happy making
