I think you'll get more advice posting this on the Theme Park Attractions and Strategies board.
So I'm assuming you've made your hotel reservation.
Step 1: You need to make your dining plans. You can make ADRs 180 days out, which is fast approaching for Nov.
Consideration A: Consult a crowd calendar and make a plan for what parks you will visit on what days. Also decide if you will attend EMH or avoid that park.
Consideration B: If you haven't already, you will need to decide if you are getting PH. I'd recommend it because it's easy to do with a group of grown ups, it offers flexibility to spend as much time as you want in each park, and if you'll be there in early Nov, you can enjoy F&W booths more than once.
Consideration C: Generally, I'd recommend planning less time in DHS-- there's a lot of construction right now. Just hit the highlights and move on. Epcot will likely command more of your time if F&W us going on-- well worth it. MK and AK will likely take the most time-- MK because it has the most attractions, and AK because Pandora just opened and, as I undestand, is worth seeing.
Consideration D: If you're celebrating some big events, consider something special at least once. Not sure of your budget, but HDDR makes a big deal about birthdays, there's a Highway in the Sky Dine around that I'd absolutely love to try (well reviewed), there's dessert parties with reserved seating for almost every nighttime show, there's signature restaurants to fit every taste, etc. Look at some menus online and make your choices.
Step 2: You'll likely refine your plan over the next months, but the next big step is 60 days out when you make your FP reservations. There's many schools of thought, but I like to make mine starting around 10 as the crowds hit. You get 3 per day, and all must be for the same park. All parks except MK have a tie ring system where you get 1 top tier attraction FP, and two second tiers. Epcot's tiering system us the absolute worst. Familiarize yourself with the tiers and plan which attractions you want when. Typically, FEA, 7DMT, and the two Pandora attractions are the most coveted and hardest to get these days.
* Make sure you have the
MDE app on your phone. You make FPs and ADRs there.
* FP selection opens at 7 AM EST. Be on your app or computer ready to start then.
* Once you've exhausted your three FPs, you can make more one at a time for any park on the MDE app. This depends on availability. I was there Veteran's Day weekend last Nov and Same day FPs were gone early in the day. I'd imagine the same is true Thanksgiving week. Other weeks in Nov, there's likely more availability.
* If you choose a FP that is late in the day, like for RoL at AK, then you won't be able to get SDFPs that day as you must first exhaust your initial 3 FPs.
Step 3: Then, it's time to refine your plan until you leave for WDW and enjoy your trip.
Best day ever!
