Have you tried reading The Article? Crimson behaves exactly the same way with the corruption so you stop it the same way.

Dayblooms don't do anything, I don't know what you are talking about. Maybe you meant Sunflowers. It's a misconception that sunflowers stop the spread of the corruption/crimson, all it does is prevent the block that it is planted on from being infected but all other blocks around it WILL still be infected.

You can only get one type of ore out of two in each world regardless of if it's Crimson or Corruption. You can see which ore you can't get depending on what your world has if you read the Ore article.
