Does normal tsh (1.49) and a bit lower than usual ft4 (0.730) means i am fine?

No how you feel and look is better guide to is you are fine. And what your thyroid feels like.

Both of your TSH and free T4 are within normal range.

Maybe. The "reference range" for a lab result is sometimes called the "normal range," and confuses people into thinking that a person is normal if her lab value is within that range. Not quite what it means! Some fine people have results outside the reference range. Some not-fine people have results inside the reference range. Numbers are just numbers, thus one's doctor looks at the whole picture.
