I had once upon a time posted a list of good foods that are high in calcium and how much they contained, but I think it was lost in The Great Crash of '04. I'll dig around and find the numbers for you again.
I do take a supplement also, just the swallow-it-down kind. And my multivitamin provides a good-ish amount as well. From what I've read, women should have around 1000-1400 mg of calcium per day. The amount used as the "RDA" on bottles and such is 1000 mg, so if they don't have a mg count on the label, it's easy to figure out how much there is. If it's 24%, that's 240 mg.
Anyway, I'll make another list
