Blacky hit it on the head: checklists are good but more importantly, have a buddy interpret them for you in a sim(profsit). Getting to know the checklists will help you in systems ground school as well as the fact that the engine is very similar to the T-34. Another thing is to go to book issue and ask Patsy for a systems disk. Take it home and burn a copy. That disk, NATOPS, and old crusty instructors are all you have to fill in the blank systems "FTI". Calling it an FTI is a stretch since it is only as good as you can fill it in with your notes. So, do yourself a favor and copy most or all of the info from the disk into your book.
As far as getting in a preflight bird, that is also a good idea just to familiarize yourself with the cockpit but the sim is better since you can start the plane and have realistic feedback from the instruments, etc. However, as it gets closer to the time for your FAM-0, definitely go to the preflight bird and practice the preflight checklist. You can do that all in one day the weekend before your FAM-0. You know, procrastinate like they taught us in college.
