Yes, Jezzrian, is right, TOSC is not so much an add-on or continuation as an expansion pack which gives the opportunity to play in new areas with new sidequests but only WITHIN the frame of the main game/plotline of BGI. And as the final battle ends that main plotline, TOSC has to played before that. The automatically created export file for your main character will only serve to enable you to import that character into BG II, but is in no way connected to TOSC. Sorry !
