So I have about 35 coins which are now about 32 days old.  I have a few questions about coinstake minting.

Do my coins have 35*32 coin days or do 35*2 coin days?  In other words, does coin age only start building up after the 30 day waiting period?

My wallet is not encrypted, when I run the client, do I get any indication that the client is minting?  I would at least expect to see some CPU activity for the process, which I don't.

Once I do find a stake block, and after I wait the 520 block stake period, do I have to wait another 30 days before I can start trying for another block?
