Fraud has to be something the court would consider serious, such as he told you he wanted children. He could not have children, or he did not disclose to you that he has a severe mental or physical ailment for which he has been hospitalized in the past and which would interfere with his familial obligations.
Spousal support will depend on your relative incomes, the duration of the marriage, and your relative health and ability to work.
He can be served anywhere by an adult who must not be related to you and who will sign an affidavit of service.
I strongly suggest you consider mediating your divorce. It is too important an event to leave to self-help.
It must be done right. You need an experienced matrimonial attorney to make sure it is done right.
