The active tiles do not aggregate emails for a start off, you need a tile for each and every email account you want to view on your phone, there is NO unified Inbox. So say you have 4 email accounts, well that is 4 tiles to look at!!!!
When you plug in your camera and iPhoto opens, you should then quit iPhoto and open iMovie.
You can then import the video into iMovie. Don't import it in to iPhoto.
If you do import it into iPhoto you can still access it in iMovie, but I find it better to keep then separate.
