Blood meal is N or Nitrogen, it helps veg or green growth. It breaks down pretty fast but if you use too much you can cause issues. How much is based on how big of a pot/plant you have.
The Bone meal is P or Phosphorus, this generally promotes root growth. It breaks down more slowly (unless you have a lot of microlife in your soil). Again, too much = problems.
I would think once a month, but I don't top dress often.
There should be directions on the box, they are usually pretty acurate.
