When you open up EAC, select the "wri" option. Drag and drop whatever songs you want there, make sure the correct burner is set, and it should be "away you go". I don't burn using it myself, so I can't really tell you anything more than that..
For burning, I'd recommend Nero. EZ CD Creator is more newbie friendly, but Nero seems to be easy as all get out to figure out as well, although not as nice a GUI to follow, but there seems to be a learning curve for Nero, whereas EZ should be able to be figured out by blind monkeys mashing buttons on the keyboard.
EAC is probably NOT the tool you want to use to BURN a CD, but to rip one....excellent!
