FYI that coil pack harness (the one that goes from the coil packs to the rear engine harness) is infamous for turning into dust, but the good news is you can get one at the stealership for less than $20. They fail so often that most dealerships include it in tune-up quotes for these cars. And a new plug wire set (make sure you get one that also includes the boots for the 2 coil-on-plugs) is also very cheap on RockAuto.

Did you change the gaskets on both sides of the TB when you took it off for cleaning? just trying to eliminate variables here.

Deleting the cat is entirely possible if you use an o2 sensor fooler or a couple of spark plug non-foulers on the downstream sensor (since the downstream exists for the sole purpose of making sure the cat is working properly- only the upstream one before the cat is used to determine where the fuel mixture is). But you don't want to replace or delete your cat unless you're absolutely 100% sure it's bad. Deleting it even doing it 'right' can still cause problems and should be done only as a last resort.

You're going to want to pick up an eBay $5 ELM327 bluetooth box and Torque Pro (and an old crappy Android phone off craigslist if you don't currently use android, Apple has locked out the bluetooth protocols that these adapters work on and there aren't any good OBDII apps for other phones) and determine exactly what's going on that makes you suspect the cat is bad, it's likely to also give you some insight on what's causing your no-start. http://www.ebay.com/itm/ELM327-OBD2-II-B...160&vxp=mtr
And I mean for the price there's no reason you shouldn't have one in your toolbox anyway.
