No they don't. At certain points in the game everyone you're not using gets their levels reaveraged based on the average of everyone I believe, but they don't level up normally without being used in battles.
Correct. When you regain a character in the World of Ruin that character can be auto-leveled to a certain point, but they never gain experience when they aren't in the current party when you're out leveling your in-party characters.
