Eric,
Great set of videos.
Just one thing on the drawerfront connectors - I've found that the Blum ones (295.1000) aren't that great. The metal plate is very thin, and though it's supposed to move in 2 directions, it only really moves well in one.
The Hafele version (part no. 430.90.320) is in my opinion far, far superior. It's bigger (fits a 25mm hole), and has a cast zinc alloy boss inside the plastic that has a much greater surface area and deeper thread. The adjustment is a good 5mm or so in any direction. Because they're bigger and stronger, you don't need to add any extra screws to fix the drawerfront to the box (assuming you use 4 per drawer) therefore making it easier to adjust in the future when the drawer is loaded and has sunk slightly, which they have a tendency to do.
I'd suggest you try one - if you do, I'd bet you won't be using the Blum ones again!
Edit: just had a look on Hafele's US site, and it appears that part is NAINA! In the US they just sell the same one as Blum...
