I know you can't tell who you're talking to online so let me be clear i'm not a shrink. I found these books skimming Amazon and bought them so I could learn to teach my boy how to not get in trouble, I hope!
I'll add one more skill suggestion- reading others (look at the face. Look at the body). Show a variety of pictures cut from a magazine. Have children describe the facial expressions and body postures shown in the pictures. When you read an illustrated story (heck, even watching tv commercials) draw attention to the charachters' facial expressions and body postures as clues to how the characters might feel. When reading stories to the children, ask how they think the charachters in the story feel and why.
