The wallet has been released and the coins are staking

What did I miss here. I was under the impression that we had 48 hours to get our coins ready to stake.

So now that I need to rush this, What is the best way to set up the transactions in my wallet to get the most out of my coins?
Turn on coin control, set change address to your wallet address, then just keep sending your coins to yourself until you break them down sufficiently. I aimed for inputs in the 100 range.
Can you please specify how this is done? what do you mean by breaking them down sufficiently? by inputs you mean you sent coins to yourself over 100 times?
