If you swap cats, make sure you get a CA cat if it has CA emissions.
If it is "Federal" emissions go Federal cat.
MagnaFlow makes a replacement out of Stainless with mandrel bends and a more efficient catalyst.
Definitely don't want to run a leaky cat!

Did they have a remote start?
Remote starters use a module to cheat the PATS (or even a chip removed from a working key taped near the interrogation ring).
Which brings us back to the keys if you don't have that module/chip.
It's the keys.
If the new PCM did not come with the 2 originally coded keys, you are S.O.L.
PCM reflash to clear keys and add 4
First 2 (master) go in a lock box.

A "Shift Kit" doesn't change programming, only increases Boost Regulator/EPC Pressure and larger holes make the shifts bleed down quicker to reduce "slip".
Not sure if this is a reading comprehension issue or the alcohol, but - I am NOT using a Ranger 5R55E shift strategy, it is the Sport Trac 4x4 5R55E strategy.
Here is the data log, it is 100% repeatable with every acceleration from a dead stop.
When an empty bed 2.3L Ranger snags "Fake 2nd gear" on a turn things get interesting real quick.
Even on dry pavement.
It will be awesome in the Foxbody Convertible!
