Ignore Mr. Malty numbers. I think its viability numbers are highly suspect. If you use it, tell it the yeast was harvested yesterday; that way you will get a better number.
Assuming you are confident about your sanitation, you can direct pitch to your new beer. That does look like a lot of yeast, I would recommend only pitching a quarter to a third of the harvested yeast. You need to allow the yeast to reproduce to get new healthy yeast to work on your beer, if you over-pitch, there will be less new yeast, and more older stressed yeast.
