Congrats! Looks like you're off to a good start. Considering this is not a backpack hunt and you'll likely have the ability to pick and choose some pieces as the weather conditions warrant, I'll give you an idea of what I would plan to have/bring with me, and you can make game time decisions based on your body and the needs of the environment/ hunt plan for the day.
Base layer: I like to have a synthetic and a lightweight merino blend option, the synthetic is generally not as warm and can wick moisture away and dry (pivotal for a BL) much better than merino when high exertion or warmer temps are in the forecast; Merino is nicer next to skin and warmer for sure, it will keep you warm (to some extent) even when its wet, so I prefer it when I can, especially on wet base camp hunts where I know I can dry it out later.
- My choices are the Sitka Core LW hoody and the Core Merino 120 hoody, but the FL Wick stuff is great as are a ton of other cheaper options on the market. The Kiln is too thick and warm as a base layer IMO for mountain hunting, it takes too long to dry being mostly merino and is unnecessarily heavy. Another tactic I started using last year are the Bryjne mesh merino layers next to skin with a CORE LW over that and I really like the versatility.
Mid layer/active insulation: The layers you have are fine and should pair well together as needed. I would probably choose based on the day between the 97 or the 240 and pack the vest as needed with either. I love how warm the 97 is for the weight but it may not be enough for November in MT. The 240 is an excellent piece as well but it's not really what I would consider an "active insulation" piece (more of a light wind resistant mid layer), since it doesn't breathe all that well, so you will sweat a lot if wearing it while hiking much. I used to own all 3 of these pieces and have since traded them in for the Sitka Ambient line and I love the versatility of those pieces for true mountain hunting mid layers; but I also carry a windproof layer most of the time, which I would suggest looking into, especially since this isn't a backpack hunt and you can easily justify the weight. Hard to beat the Sitka Jetstream for later season cold weather base camp hunts, but I also own the Mountain Evo jacket for when weight is more of a priority. However, there are a ton of much cheaper options to fill this void.
Static insulation: You have what most would consider (myself included) the best warmth to weight puffy on the market already haha. ALWAYS pack it and you should be good when you stop as long as you're managing your moisture/other layers accordingly. Maybe consider some puffy pants if you're going to be sitting and glassing for extended periods.
Pants: The Kuiu Attack pants are arguably the most popular pant on the market for a reason; they'll serve you well. I'd still bring along a pair of the Corrugates just for around camp or on super wet days though were you find yourself in rain gear all day as the Attacks could get a little warm. On that note also, I would consider some mid-layer zip offs, something like the Peloton 97 bottoms would be perfect but you could always go with merino too (I like my Sitka Core 330's for much colder/static conditions).
Rain Gear: The KUIU Chugach would be fine, I prefer the Stone Glacier M5 but I'd say that they are fairly comparable. Honestly, if I were in the market and had time to wait, I would keep an eye out for the new Go Hunt rain gear that should be coming out in the next few months; it might save you a few bucks and I'm sure will be competitive to the rain gear from the big 3-4, hunting apparel brands.
Boots: Like you mentioned just make sure that you try them on extensively and break them in before your hunt. That time of year I'm typically on the fence between choosing my Hanwag Makra Combi vs my Hoffman Explorer 400's. This next year I may pick up a pair of more flexible uninsulated leather boots for that time frame. Ill group into this category (since you didn't mention them) gaiters, I would definitely get a pair before your hunt (I've had good luck with the KUIU Yukon's, but I just this last year picked up some of the Peax and they seem super stout; I'd stay away from the Sitka and FL ones). I'd also recommend bringing a pair of waterproof/useable pair of shoes for around camp/in the truck and a boot dryer.
Socks: You hit the nail on the head, I love my DT socks. Make sure to bring multiple pairs of different warmth and thickness levels so you can adjust accordingly, your feet may swell up after a couple days of hard hiking and sometimes just that next step down in cushion can be the difference in comfortable feet vs blistering.
Accessories: Sounds like you have gloves pretty well covered; I'd add to bring a pair of either leather lined work gloves or Mechanix gloves that you can fit on over your liners. Any warm mitt you have will do you well for glassing. I would suggest picking up a windproof beanie (I like the Sitka Jetstream, but you can go warmer if you want) as well as a simple neck gaiter (I rock the FL Merino ones), they are really nice while glassing to be able to really bundle up (that wind will zap your heat) or to keep snow from going down your neck. Another clothing thing to consider that I didn't mention earlier is underwear; make sure you have something moisture wicking and test it on training hikes beforehand with your pants. You don't want to find on your hunt that you're chaffing somewhere or that your annoyed as hell that they keep riding up or flipping over your beltline.
Pack: Theres a lot of good options out there and I've tried quite a few; the EXO packs in my opinion/experience have been the best, they're well thought out, user friendly, carry loads very well and are comfortable to wear all day, plus their CS is next to none, but I sound bias haha. Biggest thing I would advise here is if you're on a budget, there is nothing wrong with picking up a used pack to save some coin if it means getting you into a quality pack. Get an EXO, MR, SG, IA, Kifaru, whatever you fancy; just make sure it is fit well to you, and you test it before hand and know how to adjust/use it. DO NOT buy some off brand pack just to save money or get into something new.
My very extended 2cents... hahaha
