5 yrs ago i had a tsh of .015 and a tsi of "96" which was "normal range." don't normal people have 0 tsi in the blood? am i liable to get graves?

TSI normal: Normal people commonly have a low level of tsi. I assume you were 0.96 which was normal. You are not likely to have graves' disease, but some people w/graves' have normal tsi's. Treatment of your overactive thyroid should help lower your potential for future problems, but they can recur.

TSI Nl = 100%: Tsi or thyroid stimulating immunoglobulin is usually reported in terms of % of average. Levels up to 130% are considered normal. The preferred antibody test for for graves' disease is TSH receptor ab. Regardless of the tsi result, your TSH was definitely in the hyperthyroid range 5 yr ago. If no problems since then, you have probably recovered from thyroiditis and have no incr risk for graves' now.
