First of all, don't worry. In this thread there are mostly trolls and miners left, basically cavemen.

If you go to this forum ( https://forum.ethereum.org/ ) you will find plenty of nice people ready to answer any questions you have.
Initially there will be traditional mining for a year in order to get a proper network up and running. After that they will try to move over to what's called PoS (Proof of Stake as opposed to Proof of Work) mining, which, depending on the implementation, should mean that holders of large amounts of ether points, like yourself, would effectively be doing the mining. Just follow the link above and you will find lots of brainy people giving you a much better explanation.
