I have a 32gb iPad and bought a few apps. But I decided to give this 32gb to my dad and get a 64gb. Can I transfer the apps I bought over to the new 64gb iPad?
Apps are specific to your Tunes account, not to the device. If you register both iPads on the same iTunes account, both will have access to the same apps. But then, when your dad buys apps, it will use your account.
