2)no,there isn't any little boy
3)no,i can't go to the cemetery ›››
Has Raymond been threatened by Salamandra and left? If so, at some point, a little boy will come to get you and tell you that Raymond needs to see you. The autopsy doesn't happen until after that.
How many sephirot stones do you have? Have you talked to Vaska lately? Have you gotten the books that Kalkstein wanted? Did you read the books? Have you talked with Vivaldi? Have you been inside the Cave in the Swamps? Have you brought the golem back to life?
In Chapter 2, there's a lot of back-and-forth. You need to talk to Vincent, Thaler, Vaska, Kalkstein, Leuvaarden, Vivaldi, Zoltan, Ramsmeat, Shani, and Raymond. Then you need to talk to them again. Then you need to get some stuff, do some stuff, and talk to them all again. There's a lot of running around, doing quests, finding sephirot stones, and questioning people in this chapter. Most of the quests in this chapter are interconnected, and sometimes you can't advance one until you've done more on another. Just keep doing things, and it will all turn out.
One caveat: Do NOT go into Vizima's Cemetery, if you get the opportunity to do so, until AFTER the little boy has asked you to go see Raymond and you've gone to see him. There's a bug that occurs if you do things in that order.
