No fee to enter Downtown Disney, but there is a parking fee. You can get a validation at various retailers.
Just the parking cost money. But if you are watching a movie the parking is free for 3 hours.
No, just pay parking, if you park in the structures you pay a flat rate but have to take the tram to Downtown, or you can park right behind Downtown by Rainforest Cafe and ESPN, but you pay the hour, but if you eat somewhere you can get your ticket validated for up to 5 hours which helps alot
