Thanks for all the replies. My pool was not replastered, just acid washed and a couple small patches. I went ahead and added calcium yesterday morning and a quart of polyquat 60 last night. Anyway, here' s my numbers now.

FC 3
CC 0
TC 3
PH 7.4
CH 130
ALK 80

So, my next question is: Should I get my calcium up to 200? The guy at the pool store said that since I was closing my pool next month that I should leave the calcium where it is until next year. I said I thought that it needed to be between 200 and 400 and he said not for the winter. He told me if I get it up to 200 then there's more chance for scale to form over the winter since the water is not circulating. Any thoughts?
