Don't underestimate the value of a good rangfinder. As a newbie you will likely have a tough time judging distance in wide open country. Also, I use a rangefinder to help plan stalks. In other words, if a buck is 800 yards and a rock between us is 500 I know I dont have to waste time ranging when I get to the rock. Flat land and sage brush wreak havoc on cheap rangfinders. Picture a flashlight on a table. The beam is not able to get back for quick accurate ranging much past 400.
Ebay has treated me and friends well for rangfinders. Take a look for leica crf rangfinders. Whatever the yardage is, it will range game at that. Unlike many others. Zeiss and swaros are just as good or better but more expensive.
I think you are probably ok on binos. Better glass will always help but that money can be spent elsewhere. I guess everyone has there style, but for me I spend way more time looking through binos than a spotter. They are a fun tool to have but a useful one is so expensive. Cheap spotters are pretty useless over 25x.
