In your mod list you show a WMS intake,
did you have to extend wires to MAF sensor
for this, intake air temp sensor is in the
MAF, double check your connections,
something might have come loose.

Readiness test fault if O2 sensors turned
off for no cats, it won't set CEL if you
get the all other faults to clear.
Don't have to worry about it unless
you need inspection sticker.

P1000 is just a PCM not-ready condition. It should clear. As for the IAT, I'd check the wiring as suggested since the IAT sensor is integrated into the MAF sensor.
