Goal 1: Find a way to create decent-sounding backing tracks for piano practice.

Goal 2: Set up to record myself playing acoustic piano along with the backing tracks using GarageBand.

Goal 3: Figure out how to capture video of myself playing, synchronized with the sound recording.

Goals met! Thanks to Mike Barnes' Complete Beginner Guide to GarageBand!
