Sanhedrin 53: Stoning or Sin-Offerings

How are other crimes determined to be subject ot the death sentence of stoning? That is, as derived from the necromancer and the sorcerer, depending on the phrasing: "mot youmtu" or "demeiham bam" -- the double language of putting the person to death or the phrase of blood be upon him. Note that the default stoning and often the default execution would be decapitation. Also, the mishnah with the list of all of the violations that would be punished with execution by stoning. Also, the cases of incest and the role of lashes vs. execution. How many double violations for one act come into place -- for example, incest plus a married woman?
