The glass panel is no different that the conventional panel when it comes to access to information. You just have to train yourself to pull the information from different places and work on your instrument scan.
Do you have Microsoft Flight Simulator? If not, spend $50 on it and practice your instrument scans on it. Don't worry about aircraft control, just focus on the T-scan and the hub-and-spoke scan.
Your other option is to find a simulator and get some BAI (Basic Attitude Instrument) training in it before jumping an airplane, since it's cheaper. I've done BAI training in 8-10 hours, including partial panel.
Go to my website (linked in the signature), there's a page on BAI in the "C172SP Flight Training Materials" file.
If you practice this over and over again, full and partial panel, you can get it done in 5-6 hours.
P.s. Holy crap that image is huge!
