Someone wants my MEID number?

I'm trying to sell my sprint iPhone 5s on craigslist. A guy contacted me saying he wanted me to send him the MEID number so he could verify it would work for his plan. He doesn't actually need this, does he? The only things that should matter at things like what type of phone it is and when it was purchased right? I read that it can cause problems if the wrong person gets ahold of that number. This sounds like a scam to me. Is it?

Syncing my iPhone with a new MacBook Air?

I've just bought a macbook air and have started syncing my iPhone to my iTunes account. I logged into my iTunes like normal but the only songs that were there were the ones purchased recently via iTunes. I usually buy my songs from a different source and put them on iTunes manually. If I sync my iPhone to iTunes will I lose all of that music or will it be transferred to the iTunes account?

Added (1). I have the exact house. It is a couple blocks away. I've actually approached the house. They brought out a broken phone and tried to pass that off as the only one they had. The police have already been reported, but they have not and probably will not do anything soon.
