Good on ya for getting boots now! That will make a big difference. I'd get good bino's and for your first trip I'd get a tripod instead of a spotter. I personally don't think you need either but a tripod is nice to stabilize everything and allows you to glass longer with less fatigue. I wouldn't buy a ton of stuff for your first trip. You'll figure out what you need and what to upgrade on your first trip. Be prepared for all sorts of weather as well. It could be 60 and sunny or 0 and blowing snow. OnX is also a nice thing to invest in to be able to track where you are and being able to mark things. Other than that, plan on having fun!
