First and foremost, the upper and lower sector stacks almost have to be congruent or your portals are going to be glitchy as hell. That doesn't mean that the complete area needs to be congruent, only the "windows" by which the view/player traverses. However, if it's view only and the player only sees one view and not the other (i.e. is only ever in the lower sector) then this isn't a major concern.
Secondly, I've covered the way to create linedef-defined stackers in this tutorial here:

I realize it's not concise and clear on how you are supposed to do it, but it's one of those things that you have to learn by doing, really. I attached an example WAD and a diagram to try and help you figure it out.
