With a Partial Action, you can do anything you could normally do with a Standard Action minus a move. You may cast a spell & move with a Standard Action. Ergo, you can cast a spell as a Partial Action.
Nope. It's stated that casting a spell is a standard action. NOT a partial action.
Logically drinking a potion is a standard action, do you allow two potions when in the influence of a haste spell? I don't.
