I'm not familiar with your '96, but an 800 rpm idle, warmed up sounds high to me. Is this what it has always been? Could you forgot or miss-connected something resulting in a minor vacuum leak?
Oil pressure is the result of resistance to flow. Either the resistance has been reduced as in a spun bearing or some other loss of resistance in the oil system (too much clearance for a new lifter?) or the flow has been compromised. You didn't possibly drop something into the engine that could be partially blocking the oil pick up, did you?
