(*) una de cal y otra de arena = literally means "one of lime and another one of sand". Equivalent in English: "six of one and half a dozen of the other".
That means to give one good and one bad; to play with somebody's feelings. This sentence is specially used in love relationships, when somebody seems to like someone, and then ignores him/her.
(1) I dont understand this sentence...
(2) pa' = para (for)
