protein question.

My LBM is 89.80 ( 44 yrs old, 121 pounds, 5'2), so should I be doing 90 grams or should I be doing way more than that? I do weight lifting, right now I can't as I just recently had hand surgery, but will be back at it in mid March. I average between 90 and 110 grams of protein. Thanks in advanced.

ETA: I did use the search, but I want to make sure I'm doing this right.
