Fellow MN hunter here.
A decent used bow set up from a pro-shop will go a long way to taking some of the rise out of the learning curve. I do my own work now, but for my first 4 years I had to have a relationship with a pro-shop, asking questions, understanding the equipment, etc.
I as well had about a 10 year break when I got back into archery 8 years ago, and compared to what I was using before, archery might as well have been a different sport.
The technology moves fast enough that many folks rarely keep a bow past 3-4 years, that's great for someone getting into the sport, great equipment typically at steep discounts. A pro-shop is going to get you set up in a way that most of the bigger retailers could not. Best advice I got was buy once cry once. The components such as a rest, release, bow sight, even your arrows can last many years, so what seems expensive today can be discounted quite a bit into the future.
Everyone has more or less said what you need, and I get wanting to start now, but give that Christmas cash to someone you trust to hold for a few more months, and keep saving. There are opportunities for late season rifle/shotgun hunts in MN because of CWD control, so you can still get a hunt in.

Go to a pro-shop and get equipment that is tuned and fitted to you properly.
September 2022 will be here before you know it, and you'll have great hunts all the way to December 31.
