Welcome Bonz,
I've hunted all kinds of animals and deer hunting is by far my favorite and I'd love to share some knowledge:
I agree with Matty on the clothes, you must be able to stay afield and be comfortable enough to have more patience than you can imagine. Besides clothes as long as you have a basic bow, arrows, and range finger (like you said you do) then my biggest focus is binoculars. Now I know they can be expensive but trust me they are worth it and that doesn't mean you have to buy the most expensive pair but I wouldn't go with the bare minimum in this category. You will hear many people use this phrase time and time again and it's something every spot and stalk hunter should live by, "Let your eyes do the walking" that means glass and glass and glass instead of walking around trying to find deer, remember these deer have the advantage by a longshot so walking around is just not gonna happen with a bow, get to a high point where you can see tons of ground and glass until you find something. Now, this is where quality binos pay off if you get a crappy pair and can't see very far then they won't be much help. Also, buy yourself a tripod, it makes a world of difference when you can remove all movement in your binos because you can see the tiniest bits of movement from far away and it also allows you to glass for very long periods of time. you don't need an amazingly expensive tripod, I use a very good and sturdy tripod and it was only $45 bucks. You're on the right path with scouting and it's the best thing you can do to improve your chances, don't be afraid to stalk a deer you find just for practice cause you'll find it's far harder than it seems. While stalking always remember to check the wind, they can smell you and even see you from farther then you'd expect, take your time and be patient, if you can master patience by glassing hours on end and taking hours to stalk a deer then you will be successful more times than not.
