Gilbert - your describing heel/toeing, which is a racing technique. I don't think it is going to hurt your engine during break in. If done correctly it will probably help it.
As for double clutching and truckers - yes they do it but they hard core, old school racers also do it. In older cars (and modern true race cars) with non-helical synchros you have to do it in order to be smooth. Basically it is the process of shifting from in gear to neutral with the clutch in, releasing the clutch, depressing the clutch, and then moving the shifter back into gear.
Personally I don't have the skills yet to be able to even consider double clutching on the track. Matching revs, trail braking, and making it through the corner nose first take up all my time. Maybe someday but not now...
