Just some more thoughts to meddle with your plans. It might be worth chucking some more soil in there for her, filling that box up to the brim, as it is pretty shallow at the moment... And while I was at it, I would be very tempted to try and slider her over to the left hand side of the tray, so that you can LST her along the length. In my first grow I started from the middle of the tray, and it was just a pain to get decent coverage, this current one though was started all the way over to one side, and it's been easy to just tie her along the length and watch her fill out most of the space.
As for the leaves, I don't trim them, I've found that if I trim leaves, it just kills off more of the leaf than I wanted... I tend to just let her squeeze them in there somewhere, now and again one gets a bit chewed, but I'd rather leave that to fate than get a little too eager with the scissors.
