Animagique in the Disney Studios is a nice colourful show. As for rides, Fantasyland is the place! I'm sure your son will enjoy most the rides there, as long as you're comfortable taking him on them.
We are a friendly bunch here so please join in on any other thread or start a new one if you have other questions
Fantasyland will be your friend with 1 year old. Dumbo, It's a Small World and storybook ride will be perfect.
Some of the dark rides - Snow White and Pinocchio - can have scary bits to sensitive children.
I have to honestly say that there are not a huge number of rides that a 1yr old would be happy on (or that i'd be happy taking them on). The gentlest rides are Small World and the Carousel.
