I can't answer all of those questions well, but for the most part Congress can not say that individuals can't engage in professions. Really their only hook into trying to exert that right would be their right to regulate interstate commerce.
That right of Congress has been expanded enormously by a long line of bad decisions by the Supreme Court. One of the most agregious was their ruling that a farmer who grew his own grain for his own consumption nevertheless could be regulated by Agriculture laws passed by Congress because his usage "affected" the interstate market. A fair reading of the Constitution though, would preclude that.
I can not make the same statement about whether states could pass some of those laws. I simply do not know the answer to that.
Obviously government can pass laws treating the sexes differently. Try using the women's locker room, if you want first hand experience in that matter.
If the old Equal Rights Amendment had passed, the answer to all of those questions would be a definite no. Presumably, you would be able to use the women's locker room too. I imagine gay marriage would have then become a constitutional right as well.
