Yeah, my lovely wife would be shivering too.
I know everybody says to just wear all your clothes to bed, including rain gear, but I disagree -- what do you do when your rain gear is soaking wet? And long pants in particular will be wet and muddy every day. And thin nylon pants don't add a lot of warmth in the bag anyway.
To the OP:
You probably need a warmer sleeping pad. The Neoair Xlite is great, but it's not warm enough for winter. You could get a cheap closed cell foam pad and put it on top of the Neoair.
You need something warm for your legs when not hiking. Down pants are awesome, but any sort of fleece would work too. This will also help extend the range of your sleeping bag, as you'll wear them to bed on cold nights.
Get a pair of Goosefeet down booties to wear in your bag. Wear clean, dry, light weight
wool socks under them. If you carry a small closed cell foam sit pad (extremely useful), put it down inside your sleeping bag at night, under your feet -- adds enough additional insulation from the ground to make a noticeable difference.
Bring something for your neck. A merino wool Buff is great, and makes a nice holiday gift
I usually bring a light beanie for hiking and a warmer hat for camp, though you could wear your down parka hood all the time.
The liner gloves are just light fleece gloves, not very warm on their own. I prefer Windblock fleece for the windblocking, and I usually take a light pair for hiking and a warmer pair for in camp and on breaks. Zpacks makes a good cuben fiber rain mitt that would work over the gloves you already have.
Jackets: You have a 1-lb fleece and a 1-lb down parka. Can you wear them at the same time? I find a 7-oz microfleece pullover works better under my down parka, and they can be found cheap from lots of companies.
The down parka is ok, not the lightest or most efficient out there. If you wanted to spend a lot of money you could get a lot more warmth for the pound, but I don't think it's required at this point.
I bring merino wool base layers, top and bottom, for sleeping, and keep them completely dry inside my sleeping bag stuff sack. I'm not sure reading your list what you have for base layers for hiking versus for camp.
