The oil pressure senders are failure prone and usually peg the gauge when they do, so it may or may not actually have high pressure.

The Purolator filter failed. It was nine months old.
Overheating it failed another freeze plug.
It was a long night.
There's long-running maintenance intervals, and then there's nine months on a single oil filter. How much does she drive?
Nine months (assuming the typical ~1000/month) is about twice what I'd consider a Purolator white can good for, and probably the oil that went in with it.
I don't have an exact number of miles but I would be very surprised if it had 2000 miles on it during these nine months.
I generally operate old cars on 4000-5000 miles or one year.
failed oil filter likely caused the high pressure reading. possibly caused the noises, (and if it did, that doesn't sound good) but the overheating? if it was running without oil and got hot enough to head the coolant, i'd think the motor would be one solid, non revolving chunk of an anchor.
the overheating might be a different issue.
How would a jammed shut filter bypass or collapsed filter make the gauge read high though? Is the pressure port before the filter on an AMC 6?
