I do not consider myself an expert on MD, and definitely haven't hunted MD as much as many on here, but a few things:
1) Decent pair of binocs, say 10X42. I wouldn't go smaller on power or objective. You don't have to spend thousands of dollars. A decent pair (Vortex, Nikon) can be found online at Cabelas, Midway, etc. for $200 ish. Some may disagree with those being "decent," but just starting out, they're fine
2) Decent rangefinder. Again, you don't have to go overboard. Same comments as above. Often you can find a package deal at the online places.
3) Get comfortable shooting 3-400 yards. Not sure of your hunting or shooting background, but I've killed a lot of whitetails in eastern woods, mostly 50-75 yards. Hunting MD in open terrain results in much longer shots. 2-300 is typical. I limit myself to 400 yards. Why? Beyond that, actually beyond about 350, bullet drop increases rapidly, and I don't practice or shoot at those ranges. Now if you get to practice at 1000 yards regularly, then that's different. Set your range limit before you get out of the truck, and don't exceed it!
4) If you're considering laser rangefinding binocs, seriously consider the ability to drop a distant pin/waypoint with the RF and then navigate to it. Comes in handy after you spot a bedded deer, or one is down and you have to cross a canyon to get to him, or just for figuring out on Onx who owns that property 1000 yards away.
5) Actual hunting? Get high and glass. Oh, not smoking pot high, but on top of a peak or rock!
Then glass some more.
BTW, did you read the fine print when you created your Monster Muley account? It said all new members must post pics and GPS coordinates of their kills!
Good luck!
