As a rookie, don't get too worried about the details. You are probably out to get a deer, any deer, and a yearling better watch his hide. What you want to do is figure out where they deer will eat and where they will bed down during the day and how they will get back and forth between the two.
If the deer are not pressured and there is food near cover, they will slip out for a snack at about any time of the day. When the deer are traveling they will use the available cover to get from where they are bedding during the day to where they are eating at night, so that's where the funnels and other things come into play. If they are eating over a fairly wide area and bedding over a fairly wide area, but there is some natural feature that will force more of them to pass through a more narrow area as they move in between, then you are in business.
Then you need to figure out how you are going to get in and get out without making the deer aware of your presence. If you expect them to be eating in a particular field then don't walk through that field on the way to your stand. Wind is very important and you don't want to have it blowing at all if you can get that, but definitely not from you to the deer. Looking at satellite images of the area is a great way to figure out where the deer are going to be at different times of the day. Once you can start to figure that out, then you are in business. Then just be smart and get there before they do without them knowing you are in the area.
When you do see deer try to figure out why they were there when they were there and where they came from and where they were going. It will start to make sense.
If you are targetting big buck, well they didn't get big by walking around in the open, so you need to be even more careful, think smaller, you are hunting one deer and they can bed in a bathtub if they feel safe, and hunt during the rut because like most guys, we tend to lose our mind when chasing the ladies.
