I can't speak to any of your first questions, but your last question I can answer: definitely make the door part of the pullout mechanism. I've had friends with kitchens where the door was separate from the pullout, and they both report that the two-step process is unbelievably annoying. This makes sense to me, given how often you open the trash in the kitchen every day, and especially since your hands are usually full of gunk when you're aiming for the trash. In my kitchen, I made sure to make it a one-step opening.

Hope someone else can help with the Rev-a-shelf and Ikea questions.

Thanks justmakeit! I was wondering if attaching the door to the pullout would make it too difficult to access the rest of the space between the pullouts.
