Don’t worry so much about the switch. Once you get into, you will find the power of FCPX that makes it much faster and more effective than FCP7.
Suggestions would be to get Ripple Training and also not try to make your X work like FCP7. I don’t even think in terms of tracks anymore and when I do edit on FCP7, PP or MC, tracks seem to get in the way.
Good luck and have fun!
