Which goes down first?

I am currently on PTU (started Tues night), but was on Methimazole for almost 3 weeks prior (got allergic to it so had to change ATD).
My results on 22 July 2008:
T4 - 22.4 (0.5-10.4)
T3 - 36 (15-38)
TSH - 0.01
Last year my T3 was elevated.
My results on 20 Jun 2008:
TSH - 0.01
FT4 - 2.82
I don't remember what the ranges were for the results on Jun 20th, but my TSH definitely hasn't changed. I know that it'll probably be the last thing to change.
Also are my results considered mild, middle, or very hyperactive? My doctor does not seem to give me enough info when I ask him. He says that my thyroid is "very" hyperactive and that I have Grave's disease. And for the life of me, I don't know how he came up with that diagnosis, because he hasn't done any kind of uptake to determine that.

Graves is the most common cause of hyperthyroidism - it can be diagnosed often by labs and ultrasound and the pattern of thyroid function.
The T4 levels are about 2x normal - so this is moderately hyperactive and certainly needs treatment. If the PTU does not work or is not tolerated then I-131 or surgery would be the next step.
