Although, from reading your story I'm not sure restricting access to Ressurection spells will change your partys fatality rate very much. I get the feeling that the Cleric is going to be problematical -- will someone who casts fire spells into the middle of the party and purposely ignores his healing abilities learn some sort of lesson from another player having difficulty getting raised? It doesnt sound like it, the lesson is too subtle.
It might be better to approach this from another angle; does the Clerics god approve of chaotic pyromania and disapprove of healing? If not, the Cleric is going to have trouble getting the spells he wants. "Oh Great St. Cuthbert, grant me this day a full rack of Firey Burning Finger spells so that I may slay your enemies and all that generally stand in my front arc." "Um, I dont think so, pumpkin. How about some Create Waters and a Mend or two? And try and stay out of trouble today, OK?"
