Two questions: brick returns above roof and how to dress up a protruding stairwell

[DRyeHD]

I'm dealing with two issues on a plan that are taking way to long.  They are probably simple fixes but I'm spinning my wheels.

 

1.  I can't get brick to display on a high side wall as it would sit in a piece of angle iron just above a shingled roof.  I'm trying to use a knee wall with a brick veneer top and 4" interor bottom.  See pictures for how it's going.

2.  I've got a stairwall that comes out into the garage as it goes up into the bonus room.  My stairs are ok.  My  problem is getting the angled pieces that cover the stairs in the garage to snap well, I don't know how to get the bottom to cover with drywall, and there is a space in the ceiling where the stairwell goes through the ceiling that I can't figure out how to get to go away.

 

I've attached pictures of both issues and the .pln file.  Any input is appreciated.
