Have you tried George at georgeb@944ecology.com (845)364-4173 ? He usually has a good line on parts for good prices. IIRC he is in NY, but he might be able to help you out. Ships quickly too.

Do the o-rings come off with the AOS, or do they stay inside the block?

hey i'm having this problem with oil 'n such. here is where i'm at so far:
is it ok just to use some carb cleaner for now to take care of all that junk in the TB and hose? or will not replacing those O rings lead to further problems down the road?

I would pull the TB, give it a good cleaning, put everything back together, drive the car, and check the TB for oil at your next oil change.
Some oil here is normal. The AOS and associated plumbing are designed to scavnege compustion blow by, so a little oil vapor will get carried into the TB.
However, if you see oil collecting at the lower AOS O-Ring, or if your oil consumption is too high, then bite the bullet and replace the O-Rings.

Maybe. These engines will use some oil, but we don't want to burn any. Burning oil shortens the life of the O2 sensor. When the sensor fails the engine will run rich, and the combination of the rich fuel and oil burning will toast the CAT. Not to mention fouled plugs and poor gas mileage.

Additionally, the hose from the top of the seperator to the intake boot is under a partial vacuum so that combustion blow-by gasses can be drawn into the intake.
When the seperator to block O-Rings leak, the partial vacuum will draw oil and blow-by gasses into the intake, with a resulting increase in oil consumption and possible plug fouling.
Other sources for similar leaks are the filler cap, dip stick O-Ring, and the dip stick tube seal.
You can get new O-Rings at you local dealer. PNs are: 999 701 613 40 20mm x 5mm and 999 701 661 40 24mm x 5 mm. Should run you about $11.00 for the set.
