Don't try learning about the glass cockpit environment while actually flying. That will just increase the cost and adversely affect aircraft handing. Initially, especially low-time, you will have your hands full just flying the aircraft. Strongly suggest you get to know your way around the PFD/MFD/GPS stuff by practice on the ground beforehand.
That said, the SR20 is a lovely aircraft to fly when you are familiar with it; the SR22 even more so !
