You'd be a small in the hooded sweater, I think that piece runs same I haven't tried it on in a year. I prefer mine over that though unless the diagonal quilting is your thing. It is a nice piece though.
The quilted one is warm but you have to remember i live in socal so i don't know if a sweater under the down sweater will be toasty enough for an ny winter. I guess it depends on how long you will be outside for. A thermal, sweater and hooded jacket no problem I would imagine.
Down shirt only goes down to "XS", which is fit for 34" chests according to SW I'm wondering how accurate that is, however, considering Tres Bien's 6-foot+ model wears a "S"
I got the California winter jacket last week. I'm usually a 38, ordered the xs and it fits the way it should. Also, it's awesome. Great modern take on traditional parkas, the details are well chosen (supersoft honey leather+copper=!) and oddly enough, I received several compliments on it. Even the tasteless idiots living in Wisconsin can appreciate how great this thing is. That says a lot.
