If your stake rewards are getting 120 confirmations, then you should be all set.
If you are familiar with "coin control" then you can take those blocks and combine them into larger blocks. I do this after a few small transactions get confirmed, so I don't lose much coin age. A few pages back, I posted about coin control, for those that haven't used it before.
As more coins start staking on the network this may become more important.
PoS is mining, where the largest blocks(having more weight) are like a PoW miner with large hashrate, and are more likely to win the block reward. Small solo miners still win rewards, because it is like a lottery, just without the same consistency.
