TGM - Finding a new job should now be your full time job. Believe me, I've been there. At least 35 hours a week. Keep a log. Network with other job seekers and keep each other accountable. Good luck.
As for your wall - if you DID overlay drywall you are right about dealing with door jambs, window jambs, trim, etc. Its a big project. As for the 101" walls. You can use 8' sheets and piece it. i would go horizontal. and put a seam near bottom or in the middle, horizontally.
