Just to clarify and post an update. Our two dogs and cat are almost ready to go. We may not be, but they are. The Entry date is
6 months from
the date the blood was drawn for the titer test. Some vets are getting confused on the issue. I spoke to the USDA yesterday. I was told to go ahead and mail the PETS Certificates (filled out by my vet) and $84.60 or $28.20 per animal to the local USDA Vet Services office. In the case of Atlanta it's in Conyers. They will in turn stamp it and send it back to me in the enclosed SASE. So there. That's it! So to keep up the Certificate all you have to do is make sure that the animals are vaccinated BEFORE the expiration date on your certificate (6 months after the valid from date "titer drawn date").
The USDA Vet can come to the airport, but she said that in most cases all travel arrangements to include the sealing of the crate by them are now being organized through the respective airlines. So that's my story so far.

So in summary:
1. Get ISO approved microchip in Pet (we used HomeAgain).
2. Get Pet vaccinated.
3. Wait a few weeks.
4. Have your vet take a blood sample and send it off to Kansas State University (A DEFRA lab).
6. Wait up to 6 weeks. Ours took 4.
5. Get blood test back. (Hopefully strong enough or above .5)
6. Have Vet fill out PETS certificate.
6. Take/Mail (I'd call first) PETS Certificate to USDA/VS office.
7. They will stamp it and give/send it back to you.
8. Make arrangements for flight and sealing of crate.
That's all I know so far. If anyone needs me to find there USDA office or anything at all let me know!
