You should be able to pull the engine codes to see if there are any problems related to the sensors. I had a problem with my Map sensor and found out about it by pulling the codes. Search for paper clip and codes.
I'm not sure but I would think that a cracked engine block could be messing everything up. I don't know if it is even worthwhile worrying about the idle until you get the crack taken care of.
I'm interested to see how your situation turns out. Shortly after purchasing my prostar ('94 TBI) I found out it had a blown head gasket. It stunk at the time, but looking back, even with the gasket problem, I don't regret the purchase because I was able to fix it myself and learned a lot in the process.
