let me give you a straight answer.......no
Yes they need to have kidded.
No, the hormones needed to produce milk are not produced until after the goat has given birth.
You need to get your goat pregnant as she won't produce milk until she has had kids.
Yes. It is safe to eat the goat meat when pregnant.
If the male goat is the father of the kids, then probably. Sometimes a male goat that is not the father of the kids will protect, but not always. In my advice, do not put the pregnant goat near any males but the father.
A goat can produce up to 16 pounds of mohair each year.

no
Nope. Only the doe and her genetics is responsible for how her udder will form and how much milk she will produce.
She could have a pseudopregnancy/cloudburst - some dairy does if they are from a high producing milking line can spontaneously produce milk when they are older.
Yes if she has been served by a buck but it is recommended that you stop milking her a month or two before kidding so that the mammary glands can recover and the cells have time to change to be able to produce colostrum sometimes depending on the nutrition you are feeding her if she is not getting enough for the foetus it is reccommended to dry her off a lot earlier.
Pregnant women can, in fact, eat goat meat. Generally, though, pregnant women should check with their doctors for personal advice before consuming it.
Being a goat. They're good at being annoying, stinky, hairy, and being a goat. Wait, I already said that one.
