Don't get too dogmatic about it. Different people have different ideas of what works for them. And different things work in different conditions. For example:
Hands -- if your gloves are getting wet from perspiration, then you need lighter gloves or none at all. Perhaps just your glove or mitten shells. By the way, don't automatically assume you need to wear anything on your hands unless it is bitterly cold. May not really be needed at +10*F if you are really exerting yourself -- perhaps just once you get above treeline, or if you stop for a lunch break. Back when I was climbing the 4,000' peaks in the White Mountains in the winter (your locale), I often did not have anything on my hands, even while snowshoeing and holding an ice axe head. I regarded that heat loss as part of my thermal budget. In fact, I tended to hold a snowball in my free hand so that I could melt it as much as possible before eating it for water. (If you let yourself get thirsty, you really cannot eat enough snow to quench the thirst, but if you eat snow as you go you can keep from getting thirsty.) Of course I "gloved up" as soon as I stopped generating so much heat. Another point about hands -- if your shell parka sleeves are nice and long, the overlap onto your hands may be all the warmth those hands need as long as you are moving, or for short stops.
Drying things in the sleeping bag -- the comments that, if you are out for a long time, you must at all costs keep moisture out of your down are accurate. However, if you are only out for a night or two, there is no reason you cannot put damp (not sopping wet) stuff in your sleeping bag with you to dry. You will lose loft, but not enough to matter (unless your sleeping bag is marginal to begin with).
Another trick some people have used to dry damp things is to fasten the damp item inside their underwear while they are moving (and generating heat) and let the body warmth do the drying. I cannot say I have done that myself -- have not needed to -- but some other folks have.
Since I gather you are inexperienced, check out available instruction -- perhaps
* a local college outing club (quality varies, some very good)
* The AMC (used to offer one, don't know whether they still do)
* The Adirondack Mountain Club's Winter Mountaineering School. I don't know how it is today, but in years gone by the ADK course was *excellent*. Well worth getting yourself over to Heart Lake for.
