They will appear in a random order, but once you have one it will not re-appear, so you don't need to worry about buying duplicates.

I wouldn't worry too much about which resource to get from the idol either. Those blueprints take forever. Took me more than 6 months before I got them all.

My only advice is make sure you have enough resources for the most expensive TWO pieces remaining as more than once I had long stretches of nothing then one showed up, I would buy it, and it would be replaced with the next piece, so two right in a row.
