Will 82-316 work for lock replacement on 200 series sliding door that was bought and installed in 1987. And, if it will, will the thumb latch need to be replaced in order to work with this keyed lock? Thank you.

The 82-316 is the newer style key cylinder. It is left handed (determined by the outside view looking in). As for the inside thumb turn, I think yours should work, but if you're not sure you can always order the 82-043 to be safe.
