If you spend some time reading the 'ROTP, RMC, CMR' sub-forum you would see that many people have already received offers for ROTP at either RMC or Civ U, which answers question #1: Yes, the first round has taken place.
Your second question will be met by hearsay and conjecture. Many people online here have heard different things from their respective recruiting centers. You will probably get several different people telling you how certain they are about when rounds 2 & 3 will be taking (or have taken) place.
Best advice: Call your recruiting center because they know more than anyone online here (minus those involved in recruiting) or just sit tight and wait, because it's highly likely that no one here can give you a definitive and certain answer.
