Also, at what point do you call a tank mature?

That is a on going topic
I would have to say a tank is mature when all levels are stable such as salinity, pH, alk and ca. Less swings the better.

I am assuming that clams like a calcium reading of 400 to 450. Is that correct?

Yes.
Also take into consideration your present tank mates and lighting.
Hope this helps.
