+1 on Flatlander's excellent post. In addition -
I would add to specifically start with 10x binoculars. 12-15x are great and praised for good reason, but with as much $ as you are going to have to invest elsewhere, and size of deer not being an issue, 10x will serve all your needs in the forest and open country. Then you can invest in heavier, more expensive deer finders later. 15's tend to overlook the deer that are already in (or closer to) your shooting range. Practice out farther than you plan to shoot. My ethical shooting distance ends when my 3-shot groups exceed 4", YMMV. Also have an idea of what your 1st, cold bore shot does compared to warmer bore shots 2 and 3. Hopefully you just need the first one.
When you sit to glass with your tripod, sit within shooting distance of expected encounters whenever possible, have your firearm ready and always keep the wind in your favor for both scent and sound. I killed my first elk 30 seconds after snoring, downwind with my back to a tree and my rifle in my lap after hiking 6 miles that morning. A quick 20 minute nap often keeps me focused for the rest of the day.
Finally, search this site for everything that comes to mind. With exception to new equipment, everything a beginner could hope to learn already lives in these forums. Here are some of my favorite threads -
