The CEL should go off on it's own if you fixed it after a certain number of start cycles (or if you had the codes erased). To see if it burned out, just turn the key on without starting the engine. All your warning lights should illuminate for a couple of seconds, then go off. If the CEL doesn't light, it's burned out. The scan tool at Walmart needs to be OBDII compliant. Unless it's a new model I haven't heard of, it is probably only OBDI compliant and the tool itself just grounds the ALDL (basically a fancy paper clip) with a book of code definitions.
