Well, if it was my truck and I knew I had a bad IAC I would probably pony up the $$$ and replace that with a new one first. If that didn't solve the issue, then I'd be seriously thinking of taking it to my mechanic and paying him for some quality time with his specialized diagnostic tools to look at the ignition, fuel injector pulse rate/duration, O2 sensor operation, etc.
