I say definitely resign, KG has won the ring now and is a loyal guy (see Timberwolves, Minnesota). He's earned a LOT of green in his career so certainly doesn't need the money, plus he doesn't seem the kind of guy to blow it on crack, hoes and gambling (see Walker, Antoine). If the Celtics choose not to resign him, he'll probably just retire. If they do then great, a couple more years of that crazy mofo and his silly faces.
