You've got a lot to fix here man. Check you coolant hoses, all of them, one could be leaking, allowing air to drawn into the system, or you could have an issue like JJ said. Get a damn fan shroud on there, along with an engine undertray, you probably don't have that one either. I'd personally not waste money on iridium plugs, I'd put NGK coppers in there gapped to spec.
