Flight following while on a VFR flightplan simply tracks you on radar, and gives you aircraft traffic alerts. In real life it's usefull in the event you end up crashing, they will have a better idea where you begin search and rescue operations because you were being tracked on radar. You still have to navigate on your own.
To fly into a controlled airport, you're going to contact the tower 10-20 miles out. I did a short flight into Felt's Field, a small class D controlled airport in Spokane, Wa. VFR flight following won't automatically vector you into landing. Open up the atc window, and you will see the options to create an IFR flightplan, cancel flight following, and an option for nearest airport list. Select 'Nearest Airport List'.

Now you will have a list of a bunch of airports. If you don't see the airport you want on the list, select 'Airports Farther From You'.

Ok, Felts Field is the second from the top. I've selected that.

There will be an option to tune to the ATIS frequency to listen to the weather, and an option to tune to the tower frequency. Select 'Tune Felt's Field Tower'

Now there are more options. You can tune to the ATIS freq, request permision to transition the controlled airspace, request touch and go, or request a full stop landing. Select 'Request Full Stop Landing'.

The tower will give you instructions to land, and in this case, i've been instructed to fly straight in and land on runway 21L. If I want, I could select another runway, and in some cases, you have the option to select different approaches. When you get closer, the tower will clear you to land. As usual, Aknowledge, land, and continue to adhere to ATC instructions. It's pretty straight forward, but I hope I was able to explain it better.

At an uncontrolled airport, you're going to select the airport from the menu the same, but instead of talking to a tower, you're simply going to announce your own intentions
