If you have specific questions to ask, I'd be happy to answer them.
"Amplitude" just refers to a complex number corresponding to a given point in configuration space. The Schrödinger equation specifies how the field of these complex numbers evolves over time. The probability of being in a particular configuration is proportional to the square of this amplitude. Does that help?
