Learn the habits of your quarry, in this case deer, While you are researching with books get into the woods and LOOK. compare what you are seeing in words with what you are seeing on the ground in the form of prints, turds, scrapes etc. The first year or 2 you hardly need to take a rifle as it is just weight to carry while you learn.
(Take it anyways as you MIGHT get lucky) be quiet, no electronics, learn to SEE, not just look, listen, deer are surprisingly noisy. In woods, you are darned unlikely to spot "a deer", you are more likely to spot a twitching ear or tail and then make out the deer from that. You do not have to wait for "deer season" either in order to practice your skills, the sport of "Deer Stalking involves simply finding deer and sneaking as close as possible.
If you master that the actual kill would be anti climatic if venison weren't so tasty.
As for gear, you don't need much, I've never used or seen used a call, or rattling, for actual hunting you will need Hunter orange (different States require different amounts, here just a hat is enough, other States require a vest) if you will be bow hunting or just stalking out side of hunting season camo is better.
You will want to wash your hunting clothes in unscented detergent . Many people I know then hang them in the smoke of Sweet fern, cedar, apple, or some other aromatic wood or brush , DO NOT use scented soap, shampoo, aftershave, or deodorant, deer have good noses . when you finally see a deer, or are approaching an area you think they are in always keep the wind from them toward you.
That's all that comes to me off the top of my head, and it only applies to lone hunting, there are other concerns if your state allows drives , such as not getting shot by your fellow hunters.
Another word on gear, if you want to still hunt from a stand, get it set up well before deer season so if they do see it they have time to get used to it, make sure it is secure and you have a good view.
One word on scent, many people use Doe urine or some other "attractant", DO NOT PUT THIS ON YOUR CLOTHES. Put it on a piece of rag stuck through your belt or some where else you can get rid of it quick.
In rutting season, if it smells like a doe a buck will try to mount it, even if it is funny looking.
Can't think of anything else right now. Have fun.
