"It is Angie and I" is correct.
When a sentence is put together this way, "It is ______," you always use the subject form of the pronoun. For example, "It was he who did the dishes" is right. "It is she and I who are going to 'Harry Potter' " is correct. When you get home and walk in the door, it sounds weird but is grammatically right to call out, "It is I!"
Est quid est.
The correct way to phrase it is "Angie and you." In English, it's customary to mention others before yourself when listing names, as it reflects politeness and proper etiquette. So, you would say "Angie and you" in a sentence.
