EPCOT - no parade at present, but the wonderful Illuminations fireworks show (so much more than fireworks!) is shown around 9pm each night.
MK - It has a parade (Magical Moments) around 3pm and on certain nights, Spectromagic (electrical parade). Also Fantasy in the Sky (fireworks on certain nights). They change these around a lot so you'll have to check when Oct. hours come out.
Animal Kingdom - no fireworks because of the animals, but a really cute parade (Mickey's Jammin' Jungle) at around 4pm - close to when the park closes.
MGM - Also an afternoon parade (characters in motor cars) around 3pm, then Fantasmic! at night. This show is a story with fireworks and is awesome! It is usually around 7pm if that is when MGM closes.
If you are going around Columbus Day weekend - you may find more parades and fireworks listed.
IMHO - don't miss AK parade - Illuminations - Fantasmic!
