The stat, temp sender, and bad connections could all be issues of their own but won't have anything to do with finding coolant on the rockers. That's not to say a bad stat couldn't be the first link in a chain of events. But still, fresh coolant on the rockers just doesn't add up unless there's a catastrophic internal failure in the head, or it was accidentally splashed in there during work.
Definitely have the cooling system pressure tested, it's a pretty simple test. If you suspect there's a leak there's no other logical thing to do first.
