You seam to be pretty capable with this project but I have a couple of attic related comments, stuff you haven't mentioned nor did I notice in the pictures...
Most house attics "breath" quite a bit and are far from being as air tight as the rest of the house. This is actually something of a problem with newer houses, which with current door and window standards can be nearly airtight. The vents in your attic allow heat/cold to escape the house, some airflow through, and by this, venting of exhaust gases or fumes.
Adding that new room could cause you some side effects. Make sure your attic still has adequate ventilation and that any exhausts (like from your bathroom fans) are piped and vented out the roof.
