Yes good points, but all DSLRs are made for special purposes and both the 7D and the D7000 were made for video. But all DSLRs have differences in video just the 1080p label does not make them close to similar. With DSLRs you get the "Jello Effect" so if you focus of a stick then move the camera back and forth the stick will appear to bend. This is just one of the many factors that you need to look for in DSLR cameras for video so I need to really look into all brands and models to find the best one. And to answer your questions I don't have any lenses yet but I prefer Canon because they are generally cheaper and better for video (Use eBay, every DSLR can be found like $500 off retail).
Thanks for your help so far, if any one has any suggestions they would be greatly appreciated!
