Learn English – What does “and are they ever ” mean

A media hog can be either someone who watches or listens to all kinds of media without paying much attention to their content, or someone who likes media exposure just for the sake of it. In your quote, it is the media exposure. It is no more offensive than its definition is: it implies that someone is vain. It is especially effective because the insinuation is impossible to disprove.

Sweet baby is a pet name you could use for a woman. When used by a man for a woman he is not intimate with, such a pet name often evokes a traditional male-female distribution of roles, in which the woman is inferior in skill and power. Emancipated women do not like this if it is used without irony. They might reply "I am not your baby, you troglodyte". I don't think it has any more specific connotation.

I sent an email to The Company of Watermen and Lightermen in London and asked them if they knew what a "stinker wharf" was and what it might mean to say that "they made bones" there. Susan Fenwick replied

a stinker wharf would have been a tannery (there were many along the Thames) or perhaps a knackery (where they boiled down animal carcasses to make glue, bone meal, etc) and so called because it smelled bad.

So it seems most likely that he meant something like bone meal when he said "they made bones."

As a side note, "make bones" (in the US anyway) can mean making money, and "bones" can refer to dice or dominoes as well. I don't think either one of those fits here.
