OK, I did manage to sneak a peek at your plan before the stupid planner crashed. I saved it to my hard drive, though, and opened it in the 2006 planner so I could work on it.
The reason the cooktop was on the floor is because you selected a drawer cabinet rather than a cooktop cabinet.
I don't think the oven placement will work. You will need to anchor the pullout to the back wall, and since the pullout is 24" deep and the oven cab is 30" wide, you'll have the pullout recessed by 6" making it impossible to access the contents. In addition to that, you don't have a convenient landing place for things that are coming out of the oven, which is not a good idea.
I did up a plan in the 06 planner to give you some ideas. Basically I used shallow pantries to wrap that bumped out wall, and put the ovens at the end of the long run of cabinets. Let me know what you think! The file is at

Here's some pix:
