Ok, nvm, I found where to get that stuff. most if the hearts can be found in Oblivion. but the vampire dusts can be found in memorial cave.
(if u dont have this on your map do the order of the virtious blood[speeling may be wrong]) but in that cave there are 6 - 7 vampires, kill them all, then about 1 or 2 days later go back and kill em again
