Since the Vet is leary of giving him another Vac she insisted we wait until Monday since he just got his 2nd vac. Are you confused yet? 
No, that makes sense, I wasn't thrilled about giving my boys a 2nd vac when they were already current.
My main question is that DEFRA won't question the time-frame from his 3rd vac and the blood test (if I do both on the same day) they only care that it comes back over the required limits?
That's right. As long as you can prove (via vet signing off on the EC 998 form) that you did it in the following order:
1. microchip
2. vaccine
3. blood draw
DEFRA only cares about the order, and that the paper you get back from Kansas with the bloodwork results has a physical sticker on it saying the result is above the 0.5IU/mL.
If it comes back too high since he has had tons of vaccination in a short period of time, will they question it?
I don't think there really is such a thing, it's just pass/fail. My boys were both over 2IU/mL and the USDA vet had no problems with it.
Also, I just have to have the vet fill out the Third Country Vet Certificate to bring him in OR am I missing something.
You have to have your vet (who should be USDA approved) fill out the first 5 sections of the EC 998 form (+ the section below for his/her signature/info). Then you take it to your USDA vet for endorsement, which starts the 4 month window for when the pet can travel (so my form got signed Jan 4, which means they're good to travel through May 4 2010). Then 24-48hrs before the flight you get the tick/tapeworm treatment done at your vet, and fill out sections 6-7, and you're good. (You'll want to check with the airlines to see if they want anything else, a lot want a health certificate saying the pet is OK to fly.)
Hope that helps.
