The ground track diamond is what you use to match up your heading with the intended course. Extremely helpful for holding procedure wind correction too.
G1000 wind vector has two options. Wind direction (with an arrow) and speed. Or, current head/tailwind and crosswind components.
For example to can either say 220 @25 or with two different arrows (one being head or tailwind, other being left or right xwind) with a number that is the current component.
One of the PFD soft keys will get you to the little pop up window that allows you to change it.
