3pi arduino robot newbie coding question

I would like to use a small menu with 3 options and use the a and c buttons to scroll between options, and the b button to select the option which will run one part of the code. what is the code needed to get this done?

what is the code needed to get this done?

When is the menu to be posted?
Can you write anything to the LCD now?
Can you read the state of the a, b, and c switches?
What "part of the code" is to be run when each option is chosen?

Have you done more than assemble a preprogrammed robot?

i havnt really started the code yet, since i dont really know how. but i will probably use if statements. if ... is chosen run this code. im just not sure how to set up the menu for it.
