TSH Test shows TSH value 0.32 L (low). What does this mean?

Your low TSH and high FT4 mean you are hyperthyroid once again.
It may be because your Levothroid dose is simply too high. But you could have a more complicated issue where the remnants of your thyroid tissue have regrown or formed autonomous nodules that are spewing out extra hormone and making you hyper.

Your calcium could be low because your one or more of your parathyroids might have been damaged in the thyroid surgery. I don't know much more than that about blood calcium and what causes it to be off.

Low thyroid is the second leading cause of high cholesterol following poor diet. If you've been undermedicated for a long time, that could be a contributing cause. If your TSH was over 2 for a long time previous to the 11/07 test, you might be able to blame the high cholesterol on under-replacement of your thyroid hormone. My own LDL cholesterol fell by 16 points - if I remember right - after my dose was optimized. On the other hand, your cholesterol problem may be unrelated. Any symptom that can be attributed to thyroid problems can always have unrelated causes as well.

I think you should see an endocrinologist. At the very least, you need an ultrasound of your neck to see whether the thyroid has grown back. And you need to know how your parathyroid glands are working. I'm not an expert on hyperT, but I know it's more complicated than hypoT. You need more expertise than a general practitioner.
