well, tackle the last issue first, 1 cord is going to cause you trouble.
I would transfer data from one drive to your comp, for temp storage, than transfer to the other drive.Or you could go out and spend 5 bucks and get another cable (always good to have more) .
ok onto the second part (well first i supose) It is just as easy as dragging and dropping into the sequence. Just brace yourself for the render. The other option is to export all your footage as dv and bring them in on the same level and get rid of that render.
