Dining Room Doorway Quick Update

The saga of my "quick and easy" project continues... I figured I could knock off this wider opening into my dining room without too much effort but I was sadly mistaken. This project has become a MONSTER!

It began so simply.  Knock a few studs out, frame the new opening, add supports in the crawlspace, trim out the new opening and add a floor transition piece.  Yeah, that grew when I was completely unable to remove the original baseboards unless I removed the (crappy) laminate flooring in the living and dining rooms.  I had planned to do that eventually but wasn't quite ready to do it now.
