Check the above link to get started on staking.
Once your coins reach 1.06 age they have a chance to be staked.
As long as your wallet is open and encrypted, all your coins not set aside can be staked.
Closing your wallet does not have anything to do with your weight. It accumulates based on time and confirmations.
Happy staking!
