From a DVM who hasn't seen your cat, I'd like to point out that about 20% of my hyperthyroid patients present for not eating - there are cats out there who don't read the textbooks.
The hyperthyroidism can definitely contribute to the hypertension, as well.
A good source of information is http://www.veterinarypartner.com (search on hyperthyroidism - they have a whole section on it there, including treatment options).
(oh, and that heart rate? I expect around 180 to 200 for the cat "being poked and prodded"; anything over 230 or so raises a red flag for hyperthyroidism for me :-) That being said, my last two patients had heart rates around 200 in the exam room).
