Hello fellow Kentuckian!
Your Disney park admission will give you access to all of the parades, shows, rides, and attractions in each park. The only things you'd need to pay for are food, souvenirs, and extras if you opt to do so. Extras would include things like a makeover at the Bibbidi Bobbidi Boutique or a behind the scenes tour.
When you say safaris are you referring to the
Kilimanjaro Safaris ride in Animal Kingdom? If so then yes, it is included with standard park admission. There are special safari tours (such as the Backstage Safari) that can be booked for an additional charge as well.
The only show you may hear referenced that is not included with park admission is the Cirque Du Soleil show La Nouba. This is located in Downtown Disney and requires a special theater ticket (very pricey!)
Hope that helps you with your planning!
