Reference ranges (specifically T3 and T4) vary from lab to lab, so have to be posted with sample results, so we can see where your levels fall within (or without) the ranges.  

Also, do you know if those are Free T3 and Free T4 or Total T3 and Total T4?  If it doesn't specify on your lab report, they will be values for Total T3 and T4.
Tests for total T3 and T4 are considered obsolete and of little value.  You should ask for the Frees, since those tell how much hormone is actually available for use by the individual cells (FT3) or for conversion (FT4).

TSH of 7.64 is higher than normal, but TSH is a pituitary hormone and does not adequately reflect actual thyroid function.  Have you had any other tests done, such as Free T3 and Free T4?  Do you know if you have thyroid antibodies or not?

Salt can cause feet and legs to swell, if eaten in excess.  There's no reason you can't eat salads and fresh fruit, although there are some foods called "goitrogens", which can suppress thyroid function, by interfering with iodine uptake.  These include cabbage, broccoli, cauliflower, kale and other cruciferous veggies, as well as some fruits.  Please note that cooking these foods removes their goitrogenic properties. All types of soy products should be avoided.  

That said, many of us find that eating these foods has little effect on thyroid levels.

Iodine can often make things worse, if you have an autoimmune thyroid disease, such as Hashimoto's Thyroiditis.  You would need to get antibody tests to confirm/rule that out.
