Here is a link to a photo of the Zodiac Wheel, translated into English, and it's by Zeppster497, so I'm borrowing it for now because it's the only one I know of. If anyone wants to make one of their own, we will post that one instead of this:

How to Use the Job Wheel
When you select your characters' job classes and their license board, the zodiac wheel will come up first.
1. Use the Directional pad to move the wheel from symbol to symbol. Each highlighted symbol will also appear in the middle of the wheel so you can see it better.
2. Hit Square button to view the symbol/license board you have selected.
3. Compare each license board with the English translation by Sephirosuy (see the FAQ sticky topic here on the IZJS Discussion Board). A good way to begin to view them is to see where the initial Battle Command starts for each character, and then scroll around the license board to see what that job will get.
4. Hit X to exit each board and go back to the directional pad to spin the wheel and view another symbol/license board.
5. If you want to select a job, exit the license boards by using X button until you are back at the wheel. Make sure the symbol/job you want is highlighted. Click Circle to select. Move the arrow to the FIRST (Yes) selection and push Circle again. If you change your mind, select the Second (No), and then hit X to go back.
Once you select a job from the wheel (not from the actual license board, from the wheel), then you can click on the license board and start buying licenses.
Your selected job will have the character's picture underneath the symbol on the wheel. There are shrines associated with each of these jobs in Japan.

Some things to keep in mind:
1. Characters come with a few skills already, regardless of the job you pick.
Vaan: has Steal, wears a dagger
Penelo: has Cure, wears a dagger
Baltheir: has Steal, First Aid, Libra, wears a gun
Fran: has Cure, Fire, wears a bow
Basch: initially has nothing and is half naked (fill in later)
Ashe: has Cure, wears a sword.
Keeping these initial skills in mind, you can easily get through the Barheim Passage and Bhujerba without having Ashe and Penelo in your party. Fran's Cure is very handy, I was worried nobody would have a Cure spell without a White Mage.
2. Check out Magics and new Break Attacks to make sure your party has most every type of spell, if possible. You will have to give up something, hopefully it is nothing you will miss.
3. Missing skills can be made up with items, game has lots of new items.
4. Interestingly, Penelo's initial job, if selected while she is in Giza with Vaan pre-palace, does not show up as selected when Balthier and Fran join the party. There can be a second person with the same job as Penelo.
