The Ripple Training advice is a good one. Get it and get into it. Got me to working with FCPX how it was designed, not trying to make it work like FCP7, PP or MC.
I think organization is a key thing too, as in any NLE timeline.
Since FCP7 is dead, your choices, outside of X, are (basically) down to MC (slow and old, with ancient effect and titling modules, just to name two) and Premiere, which still hasn’t convinced me it’s for real and seems to always be on a verge of a crash (I am working with CS6, to be fair). There is no perfect answer. Most of us use a combination of them all. Good luck!
