Well, just for a random follow up:
I called and spoke to Toyota about the TSB, but since it was not replaced at their dealership, they won't cover anything. I figured as much, and made sure to tell the lady that the service writer came back in under an hour with an initial estimate of 2800$ for just the head gasket and mentioned NOTHING of any TSBs they know of (I used to be a service writer for BMW and that was one of the FIRST things I looked for when dealing with a customer's car). Also, since that was the initial look, a new engine would have run me over 8000$ installed. The rep even chuckled a bit and said, "Yeah, Toyota dealership prices are pretty expensive." I told her that Toyota will never see anymore of my money due to this pathetic lack of assistance for an obvious problem with their 2AZ-fe engine design. But, oh well.
Engine is running great, thus far. Not really sure how many miles I have exactly now, but whatever. I just change the oil and drive. When it dies, I'll most likely get another vehicle anyways. Jeep for the winter and something fun for the rest of the year.
Here's a shot of the car with the Eibach's on there as well:
