1) You can schedule a c-section, but it comes with risks, so I personally would advise against it, unless there is a medical reason.
2) I don't live in the States, so I can't say, but it should be enough, depending on your lifestyle. Make a budget and try to stick with it, that should help. Also, see if there is any medical aid that you can get so that you don't have to pay for everything out of pocket.
You can come over to the January board, which is where most of the active members are, if you need to ask anything else.
