Answer

カードはありますか is right. You wouldn't particularly say カードがありますか. But you can say カードがあります. 
In the 2nd example, 
これは本です。 means This is A book. 
これが本です。means This is THE book. 
が is stronger than は. I know it's kind of confusing but が puts more emphasis on the subject.

For instance if you want to say "This cat is cute."
You can say　
この猫はかわいい。which means This cat is cute, but all the other cats could be cute as well, not just this particular one. 
この猫がかわいい。This puts more emphasis on the fact that this particular cat is cute.
