Thanks's for your great answers.
I'm really curious to find out if PT is going to give my mixes a new perspective or improvement. The first impression of course is "... damm I'm too slow that's not good
but I have to go through it.
I also want to make a physical and mental "break" between the composing/production stage and the mixing stage (with projects where I do both jobs). If one stays in the same DAW you tend to make less decisions.
N.B.
Concerning the import/mono/stereo thread - maybe you guys already know this software:

I tried it and it is really easy and quick.
