Hi Brent can't offer much in the way of advice since you pretty much did 
all you could
besides changing the cats and O2 sensor. (These are EXTREME measures IMO)

FYI,  I just passed my Ontario E-test on Wednesday.

I'm runing with *no* cat, "old" oil and and 7a Exhaust cam.

When it came time to swap the O2 sensor (approx 11months ago), I bit the 
bullet and bought
OE new for twice the price of the "generic".

My levels were approx 30-40% of the maximum allowed limit.

The car btw is an AAN'd Cq.

(Naysayers of the 7a exh. cam not being able to pass emissions be damned!)

I live in Ontario and here we have to do an emissions test every 2 years. 
This year, my car has failed the test.  Initially, I just took the car in 
thinking that it seemed to be running well, fuel consumption was normal, 
not burning any oil and the power curve seemed normal?

However, on the first test it failed on the Idle test for Hydro Carbons -- 
approximately 50% higher then the limit.  So I have heard that cars test 
better if you take them for a long highway run before the test... so I 
took it out for a 40 minute highway run... it was good and hot, then I 
took it right into the e-test facility and they took it in 5 minutes 
later.  It tested considerably better, but still failed!  This time only 
about 20% above the limit.

So I called my mechanic and he said he had a sure fire way of passing 
those e-tests... he said to change spark plugs, change the oil, replace 
the air filter and then put in a liter of Methol Hydrate into a tank of 
Sunoco Ultra 94 gas.  He said if nothing else is wrong, then it should 
pass with flying colours!

Well I did all of that and it failed with even a lower Hydro Carbon 
reading at Idle, then the first test!  So now I am not sure what to?  The 
only other thing that I can think of is to change the Oxygen Sensor.  I 
had this sensor changed the last time I had an e-test 2 years ago.  It is 
one of those Bosch 31913 units that was spliced in (half the price of a 
sensor with the correct connector).

I have run the VAG-COM and it does not kickout any Fault codes?  So does 
anyone have any ideas on how to diagnose this problem?
