Could be a lambda sensor problem causing the poor running.
As for the idle problem it could be the ICV (Idle Control Valve) needing cleaning/replacing. Try the MAF (Mass Air Flow) too.
Start the car and leave it idling
Unplug the MAF and see what happens
If it dies and stalls the MAF is ok
If there is no difference the MAF could be faulty.

Cat could be at fault. Although when they usually break down they block and the car struggles to rev past 3000rpm. I think on yours the cat is in the downpipe.
