Learning to hunt is an experience in and of itself.
Check your seasons for where you're at, and find some land to hunt on.
As for field dressing, it's quite simple, though there are a couple things you want to be very careful with, especially glands and waste production organs.
Frankly, youtube has been quite helpful in my learning curve there.
There's a few great vids on there which essentially are tutorials in field dressing a deer, from start to finish.
As for doing it "right", you'll know when you drop your first deer.
I suggest doing a few things though:
1) Shoot, shoot, and shoot some more. Never can practice enough.
2) De-scent your gear. There's a great recipe for homemade scent killer in the forums someplace. I don't remember where though.
3) Find the deer. Deer need a few things to be happy. Food, water, shelter, bedding area. Find their routes between any of these, and you'll be doing what the rest of us do.
4) Be aware of your wind directions - you ALWAYS want to be set up downwind of the travel paths so you don't get winded, and burn the spot.
Do that, and the deer will move elsewhere...and you'll have to wait a couple weeks for them to return.
5) Get out there and hunt!
